Toronto, you were on your 42 - 45 day without a single drink, right? This is important for you for the future, I know it is for me. After six weeks the adverse effects of alcohols are (almost) gone and you feel fresh, invigorated, powerful and ready to deal with anything in your life. Including the drink. The last one is always a mistake.
I come to believe that the vigilance over every dangerous situation (like to one you had) is the key for the sobriety. You could have had the same party and enjoy yourself without having a drink only if you PREPARED yourself for such situation and made a decision, up front, how you're going to handle it.
You simple let yourself into the trap. But, as Talluleh has said, what you're doing is great, you're the man, man
.
Good luck.
