What is my real rating, lol...

Yeah, depends on how much you drank, and how used to it you are.
It's probably impossible for a person to lose more than 300 or 400 points off their rating, unless they really go overboard.
I remember one time I drank too much while playing, and I was in a winning position, but needed to throw up. I moved as fast as I could, won the game, ran to the bathroom, and puked.
I don't drunk that much anymore.

I might get some study material cause I played my friend who is 1500 rated and beat him when I was sober. With ease too.

Your stats say you have over a thousand games played here.
Did you play them all while drunk?
That's kind of sad
I’m rated 1000 in blitz... however, that’s me playing when drunk, I don’t really play at other times. If I was to play sober and full focus, what do you think my rating can reach?
