It actually went very well :-). I think the main thing that got me through the night was wanting to tell you guys I was successful :-)
I was offered drinks a couple of times, but was able to point to my huge glass of Perrier and say "I'm good thanks". The friends I mentioned were indeed completely toasted. But what I noticed in being sober is I really didn't enjoy them in that state and I just stayed away from them, every once in a while wondering if I repeated myself when drunk as much as they did?? Yikes.
I spent a lot of time people watching, which included five adorable children trying to catch the lights on the dance floor. I'm quite proud of myself. I can do this!!
