I'm not sure from the medical side, but from experience with my husband, I'd say odd things happen.
Anything that happens when he is drunk (really drunk) is completely forgotten. He breaks things, smears dog poop all over the house, lets my tiny dogs out, leaving every door in the house propped open, empties entire closets into the middle of a room, writes very incoherent, nasty, notes, wakes certain unfortunate individuals in our home to yell at them at 3:00 a.m. (usually me), etc. blah, blah, blah.
Any conversation we have has to be completely repeated on another date, as if it never took place the first time.
I think after awhile, blackouts happen even when they are not drunk, and we do have a lot of forgetfulness..... But I'm not sure about that, so I'm sure the experts will be along soon.
Take care of yourself.
