Well I'm back home. Disappointed myself even though I didn't drink - I ended up going to the bar but just had a Sprite. The atmosphere was just so happy and I really like all these people, we were all having a great time so I just said to hell with it, I'll put my will to the test. Had a sprite and didn't even get charged for it.
It blew my mind that not a single person questioned my drink or asked why I wasn't drinking. Seriously - I'm still really, really shocked. I did duck out early, I know these guys were going to stay until bar close. They were hammered by the time I left. I still had a great time sober.
Overall I am happy I didn't drink. I am extremely mad at myself for not going home after dinner. It did cross my mind a few times "1 beer won't hurt". Then I had to internally rationalize what that 1 beer would lead to, in order to make my logic go full circle and decide NO. I don't really want to put myself to the test again anytime soon.
