My boyfriend and I have been dating for over four years now and in the past couple years I have noticed some really strange behaviors of his. They began to occur more often after he started his graduate school pharmacy program and is under a constant amount of stress. These behaviors are generally more prevalent and extensive around times of stress (i.e. before an important exam). However, they also occur after he takes a nap or is woken up from sleep. The strange behaviors include:

*semi-slurred speech
*a glazed look over his eyes
*exaggerated pauses before answering questions/responding
*strange mannerisms of the hands and face
*confusion/ somewhat drunk-like behavior
*just generally NOT acting himself AT ALL
*this weird behavior tends to last for a few hours, not just minutes

He also snores very loudly and talks in his sleep (but these are minor issues compared to his half-awake-sleep-drunkenness). I have been searching the internet for quite some time trying to figure out just what is going on with him. It scares me that he may attempt to drive in this state of mind. For now, these behaviors are little more than a nuisance to me, but it does make me nervous as to what he may do in the future.

Has anyone ever heard of this happening? If so, what the heck is it? Are there any treatments? Is there any way that I can "wake" him (even though he is "awake")? Help please!! !!

I would appreciate any advice or opinions
Thank you!!
