Another day down though! You're still probably not in the one day at a time deal, I know I am taking it hour by hour right now. then we graduate to days, weeks, months and then years. I had a year and I promise it's great.
As for personality, I am far less outgoing when I am not using. When I was, I always had girlfriends, always talked to girls wherever we were, most of my friends hated that I had such confidence, little do they know, it really wasn't me. Without I am pretty quiet, really shy and just kinda like you described, feel pretty awkward in most situations. But as everyone here will tell you, it all gets better. just keep on going!
