Probably not, I never believed in blackouts until I met my husband. When we were younger we used to drink more often being young.
Well I found through a few late night issues and next day conversations, that it is possible for some people to get too-drunk and not remember a thing. Usually the memory loss is from a certain point during the night, like in my husbands case if he would nod off for even a few seconds, when he woke back up he was still drunk ,usually more aggressive or moody, and from that point did not seem to ever remember what he had done. Be it fun and enjoyable or not.
I never noticed it while he was drunk until it had happened several times and i started watching for it.
