I understand the unreality thing. On a day to day basis my experience is like Soberpotamus described... things are real and concrete in a way they haven't been in ages. But overall, yes. Sometimes when I did or said something while sleepy, for example, the next day it feels similar to if I'd done it drunk. Or sometimes when something slips my mind and I'm reminded, I feel as though I'd been drinking and forgotten. Even moods sometimes feel to me like drinking. I do have dreams fairly regularly where I realize that I've been drinking this whole time and just lying about it. Those are intense.
