Glad it went ok Gray.
I reallllllly have to echo Dee's latter post reinforcing our first ones
I know so many people who go thru an occasion without drinking, and think along the lines of "that wasn't so hard" or some version of I can totally handle this....and before they know it, the next time they are in some situation and "all of a sudden" drink. It just takes time to get thru our heads that we can't drink, always have a choice, and to build new habits around pretty much everything.
I'd also venture that perhaps thinking about what the outing was like (good like you not drinking and bad, like the annoying ladies) and what you did right....and thinking about the very next social thing you have planned. Even if it's a week away. Or a month. Or, maybe you used to have dinner with friends a couple of times a month and it's about time again. Play that next event thru - I'm basically getting at the mind shift and ways to begin your sober life.
Are you working a program to support recovery?
