Thanks all for the advice/concern. Naltrexone is a pretty fantastic drug so far - I wish more people knew about it.
Social situation last night - guys night with lots of drinking all around. Took 50mg at 6:00. Cracked a beer at 7, waiting for my ride. Didn't finish it. (Never happened before) drank at a slightly reduced rate at the party, maybe 12 drinks total, and never felt really drunk/buzzed. (With my tolerance, that's about right).
I DID feel a bit of craving for more - as in, I NEED more - at around 11. Took a half dose of nail and that went away pretty quickly. Left (not driving of course) at 1:30, completely lucid, and got home with no desire for a nightcap. Remember going to sleep.
Without nal, last night would have been a blackout for sure.
Woke up naturally feeling better than usual, had a great morning with no hangover. I got irritable around noon - small things were bothering me. Stupid stuff really. But I did a lot to fix/help instead of just bitching, which is an improved pattern.
1.5 hours of vigorous exercise, which felt GREAT. It's been months since I've done that. (The book calls for a washout day before positive programming, but I don't see many washout days in the near future so I figured what the hell?)
Took my nal 20 mins ago, because, Saturday night and all... No real craving, but I will crack a beer in 40 minutes and see if I can have a 'normal' night of drinking. (Normal by standards different than my own

. Maybe watch a movie and actually remember it?
As for the w/d's, I have benzo's and a bp cuff from a previous detox on hand just in case I wander into dt land. I'm hopeful for a gradual taper. For the past few months, I've been taking .5 mg clonazepam in the morning and again at lunch, just to keep the sweats/shakes at bay until I start drinking again. A sadly typical routine. Interestingly I didn't feel the need to take my lunchtime dose. My head is clearer today than it's been in... Years?
I'm anticipating a long road, but grateful for the help of Naltrexone.
Thanks all.
