That sounds a lot like my problem. I loose things and can't remember putting them away, but when I look they are usually in a logical place. I do not have apnea and if I had the doctors might not have looked fruther. My doctors were just slow to take off my equipment when they noticed my brain waves showed I was asleep, and I was physically awake. They kept me the rest of the day and observed and played games with me. I didn't know what they had found of course till the next Dr. Visit. Anyway if your brother in law is like me they wouldn't have noticed it cause they would think the apnea explained everything. I know a lot of people with apnea though, and I don't think it explains any of your brother in law's problems.
In any case the meds for this condition didn't work well for me. Once my initial attack was over I discontinued them. I tried treating myself herbally and that worked better than the prescribed meds, but the problem with a condition like this is that there are times I just don't have the energy to care, and so I forget, and can't find, don't buy my medication... especially the herbal stuff. I don't need it all the time, and though a simple energy product helps I don't always take it.
The doctor put me on Concerta (like Ritlin) I didn't like what it did to my psyche. Due to other problems I had, I considered it wasn't a good idea. I get relief with Gensing, Suma, or Rocket Fuel. Any intense energy product works to a degree. Last time I tried Cran Energy juice with some success. This time I have been sick other than being exhausted, and hated to take an energy product considering I really shouldn't be too active anyway. IT drives me crazy to have to rest when I am on some of these products.
My other problem, or really not a problem, more of a situation is that I am multiple. I consider him a gift not a problem. I haven't always understood about my other self, but I've always had him. I am multiple, but we operated so closely that it has never been a problem till I got sick after my daughter was born. Before and after the birth, I had a lot of stress, my husband was being a pain in the butt, and we had a lot of financial problems. I had a difficult delivery, and nearly bled to death. I really think I might have died on the table, and I was OBE for a long time... but I didn't tell anyone. I've always been trippy and seen things, and I have always hid it. When I have experiences I can't explain I really don't try to tell people about them. I've been covering for visionary experiences all my life. I do know that I was aware of being in heaven for many years after this happened. I was also intermitantly aware of being here, and since then it has been a gradual transition into my own body.
Now I do not consider multiplicity a disorder, and I never had blackouts till my second child was born, though he has always been with me. The drugs did cause problems with my multiplicity though. My other self reacted strongly to the speed (concerta). He became very talkative, and I of course couldn't control what he said, even when I was aware of it. It was really uncomfortable to him because he just talked and talked and couldn't stop. I stopped taking the meds after a year. What he said was OK but he was like any person on an over dose of speed, chattery and nervous. I felt OK and just awake for a change. It really didn't impact my side of the persona at all. We becaome co-aware during that time though, instead of him running things. I think the speed woke me up, but it didnt' make me feel a lot better, It hit him harder and he was a nervous wreck. I got minimal results and needed a higher dose, while he became overly hyper at least in speaking. Neither one of us felt like being hyper physically.
HE never wanted to take over my life. He only took over when I couldn't go on. He could barely function within my exhausted body, but he functioned more than I was able to. In the two years between giving birth and getting ritlin, he said the effects were like being on drugs... I mean before the speed. my mental state was like being on morphine. I had no tolerance to that, but he managed to function in it.
The only reason I am telling this is that, I think maybe your brother in law could be multiple. I functioned well till I got sick, and he apparently did too. Now he has some disorder that is causing him to black out and obviously a sentient consciousness takes over when he is blacked out, that isn't him.
There is a huge stigma to being multiple, but for me it was a god send. I really think without him I'd have been in a coma for years. I might have died. My other self works hard for me. He does things the way I would have done them, and occasionally both of us make mistakes, but he tries. I have always had him.
I remember several incidents when I was younger, but only when I was in danger. I spoke of myself in the third person, and had no control of what I was saying. I was very aware of it though, and still remember what he said word for word. He protected me from a pedophile when I was 7. I never even realized till later what the guy was up to. I was very confused by the incident, because I didn't know what I was saying at seven age7. I didn't know about sex at all, but a teacher commented on my underware, and tried to lure me away from the playground. Suddenly I said a lot of things I didn't understand at the time. My tone was so loud and out of my normal voice range that my throat was sore for days after, but we got help. A croud gathered because of all the yelling. He said, "Why are you trying to look up my little girls dress you pansy. I thought you only like little boys...." (then there were a lot of words I can't type here. these words were things I'd never heard before, but he used them correctly.) Then he said, "You better get the H*ll out of here before you get hurt." In my own mental processes I felt that I was being instructed on how to take down a full grown man if I had to. I heard "how can I kill him from within this little girl body?" and then I started getting instructions. MY own mind was tangled up with why did I just call this guy a flower? I'd never heard the word Pansy as anything but a flower. A few years later the teacher was caught seducing young boys. I didn't know any of this though at the time, and had never even spoken to that teacher before.
My other self has helped a lot and he doesn't push to be in front. He'd rather stay in the background, but my physical condition forced him to take charge after the baby. I was aware of his actions, but never understood what it was, I called him my masculine side, and my uncontrolable temper, depending on the circumstances. He could always conduct an impressive verbal asault, but rarely became physicallly violent. Even when he did, he was controled, and never hurt anyone it was about intimidation. He picked up one of my old boyfriends by the shirt collar once, but that was it. The amazing thing was that I was driving at the time, and picked him up with one hand, and over to the side, it should have been impossible. I wasn't even looking at him at the time. Yet when I did turn and look his head was bumping against the headliner of the car, and his butt was out of the seat. My hand had him by the collar. That boyfriend always claimed that he was visited by my ghostly older brother.who warned him to treat his little sister right, or else. I just thought it was strange cause I don't have a brother.
My husband and children were already well aware of him. I suddenly understood things my husband had said about having his wife and his best friend in the same body. He'd known since before we married. My daughter said during my colapse, he was the sensible one, but she resented him because during that time he was there instead of me. She described differences in his behavior and mine. Just little things like the way he held a pencil, and the way he sat. She said he tended to perch on his chair sitting forward, while I tended to slouch and lay back. His personality was different, but he didn't do anything that wasn't condusive to my life.... well he turned my husband down for sex, but I can't blame him for that. LOL
He is a great help to me, and I dont' consider his presence a prolbem. Fruther multiplicity is very common, it is just that most people who are multiple function, and have good communication between the two people. Ordinarily he and I are co-aware and unless there is a problem, I do the talking. He isn't responsible for my blackouts, he just takes over when I can'[ tgo on. In the rare event he thinks I am in danger, I feel a little urge like, "may I" all I have to do is let go and he handles it well. He has only done this in the case above when I was a child, and in handling school bullies, and out of hand dates. He is quite effective in dealing with stuff like that.
I believe that he is a seperate soul. My husband believes I developed his persona out of grief at a lost childhood friend, and I think that is a valid theory also. I do know that wherever he came from, he is helpful, and not the problems, but I thought I would mention it since your brother in law has that problem. I know many multiples on line, and many of them have problems like this from time to time. I don't think sleep apnea is an explaination, mini naps might,, but muliplicity would. I consider multiplicity a gift, not a bad thing at all. Most multiples are high functioning, well paid and hard working people. It is only when they develop problems that mental health people get involved, and then they blame the whole problem on the multiplicity. I wasn't abused as a child. I had an idealic childhood. My life was fine till I went through some sort of physical and psychological illness after my second child. The only thing he may have done wrong was cover my illness, but that is what I would have wanted, and he knew that. Overall he is very responsible. Normally I would not bring up my multiplicity on this kind of forum, but I would like to suggest that maybe your brother in law do some introspection, and try to gain a communication with his other selves if that is the problem. Sometimes people don't LIVE with us, they just pass through like a channel. Some people are just and open channel, or under certain circumstances become one. It is possible that he was about to black out, and something else just took over and unloaded the load safely, not knowing where it was supposed to go, and only wanted to prevent an accident. It may be this entity was passing by or was a silent resident of his subconscious before. I think it is good that the crane was unloaded without incident, even if it was hard to find the goods later. It is possible he has an underlying physical condition, and that needs to be addressed, as with myself. Diagnosis is a hard thing to get from a doctor though, so maybe he should just eat right, take his vitimines, and hope for the best.
