I'm not sure if this happens to everyone, but I dont really get black out drunk.
What happens instead that I wake up, I don't remember shit, and then like....I get flashes of all the shit tha happened earlier before.
btw, I had my first alcoholic drink about two months ago. I might just be a noob.
Some don't get the black outs. I've been drinking for almost 20 years and there is only one occasion 15 years ago I don't remember what happened. I remember having some girl's toes in my mouth and watching teletubbies the next morning.
And in my experience the newbies are the ones who get blackouts. The more experienced you are, the better you tend to regulate.
