Thanks everyone!
Just more of the same to report here. A couple of weekends - one lighter than the other, but both controlled. Weekend 1 had an early start Saturday and a laaaaate night, so I did not feel good Sunday. This was heavy drinking, to be sure, but kinda "controlled" heavy drinking. I wanted to be out with my old friends. I enjoyed their company and drank plenty but didn't start hammering drinks and blackout or embarrass myself. This is more than I allow myself on a normal basis, but I expected that going in. I think I need to remember to buy light beers to bring to these parties so that I always have something to turn to when the hard A starts flowing freely and those around me are getting sh*tfaced.
Other positives and notes from weekend 1 - I seem to start to lose protection from the nal at around the 7 hour mark. At hour 6 I took a second dose, which helped a ton. I'm not usually very hung over these days, so this was a reminder of how sh*tty I can feel the day after. Nicely, without the reward/rush circuit in overdrive in my brain, when my buddies headed for the hair of the dog on Sunday morning I wasn't tempted to join in. I'm sure it made my hangover worse than theirs were, but my Monday was probably nicer

Weekend 2 - Same group of friends but milder. Had some drinks Friday, had some drinks Saturday, but rested plenty both nights. here I am Monday, clear headed, feeling good.
So there you have it. I am still a drinker, but I kept my **** together, and barring anything unusual happening, I won't be drinking (or really even thinking about drinking) until probably Friday.
Keep up the good work everyone out there.
