I have been having a MAJOR issue with my boyfriend lately. For the last four months, he has exhibited some strange symtoms. He will appear to "fall asleep" in the middle of anything. I put "fall asleep" in quotations, because at this point, I'm not even sure that's what he's doing. He could be in the middle of eating, talking, standing, playing a game, etc, and all of a sudden his speech with slow/slur/stop, his eyes will close or almost appear to roll back, his mouth will open, and his head will drop down. Seconds later, he will snap back to "normal". Sometimes he will instead just walk around with half open eyes and almost appear "drugged". The most frustrating thing is, he doesn't even remember or realize that he's doing it. I can tell when he is about to enter one of these episodes because it's either preceded by an episode of some form of mania (meaning he will be overly excited and hyper, sweating, etc) or by slurred/slow speech. It also appears to happen at around the same time intervals (from 6 p.m. - 9 p.m.). It actually has become quite a strain on our relationship because he has had these episodes in front of my family, in front of my boss at dinner, and just about every other inopportune time possible. Some people have even thought he might be on drugs.
I have confronted him about it, and most of the time he denies it. The rest of the time, he has fed me a million different reasons for his behavior, including medications (blood pressure meds and/or xanax), blood sugar/eating problems, and the latest: insomnia. He stopped taking Xanax months ago, but the symptoms have persisted. I have never noted that he has trouble sleeping, because when he is around me, he's constantly sleeping. He claims this is because he is "comfortable" with me and doesn't sleep otherwise when I'm not around. What I'm really wondeing is if insomnia can really cause all of these symptoms, or if I should be worried about something deeper, like drugs or serious health problems. He has had a host of health problems, including an enlarged heart and even early colon cancer (which was treated). He also has had a past history of using steroids.
I would appreciate any kind of insight I can get, even if I need to post this question elsewhere. All of this is really starting to worry me.
