Vodka memory loss (read first)

Okay, I know that when people drink alot they often forget what happened.

But the first time I ever got REALLY drunk was on kersh. I forgot the whole night, to the point where when I went back in to the room that the party was in the next morning, I felt like I'd never seen it before in my life. I apparently spent the WHOLE night throwing up. I lose my memory at a point which is APPARENTLY -exactly- when I started throwing up.

I wasn't too weirded out, cos I'd had a lot and it sounds normal.

But I've been very, very drunk many, many times since. And never thrown up. I used to drink like half a litre of vodka on a night out, and could NEVER remember anything, but wouldnt get hangover or feel sick.

I made a load of stupid mistakes when drunk.
I slept with my best friend who has a girlfriend (not sure if it was consentual), I did cocaine for the first (and only time) the week after WHILST crying about that incident where ANOTHER guy friend who has a g/f tried it on with me because I was hugging him and crying explaining it all (but I had the sense to turn him down, thank god). Then I told our mutual guy friend what happened when I was drunk and he HUGELY fell out with me. And I couldn't remember ANY of this stuff, until they reminded me. In the first case I woke up in hiss bed, so it gradually came back to me. In the second case I was gettinbg flirty texts the next day and was really confused, until he exlained. In the last case, I was blissfully unaware he was even mad until he angrily approached me and told me what happened and it all came flooding back.

I SWEAR I'm not exaggerating. My memory just GOES, but then comes back when I'm told. Also, I can often remember bits before and after the stuff I hate about the events.

Does anyone else get this? Is it physical or emotional?
