as for alcohol:
it let me turn my brain off
it made me less serious AND less bitchy
it gave me something to do with my hands in awkward social situations
it was a shortcut to making me the me that I need to be in a lot of situations... someone different
I got a little too dependent and had to teach myself to deal without... such is life
I was never much of one for the illegal drugs because they always made me fall asleep AND made me nauseous
I'm still a smoker... it gives me something to do with my hands and an excuse to go outside just to get away from it all... sometimes that's really quite necessary...
