RogerD,
I'm the exact same way. Sometimes I make it to 6 or even 10 days then I cave to the AV, ignore all the damage alcohol is doing to my body and relationships and drink a six pack or more. I slipped up on Saturday and did that. I ended up in an argument with my wife because I wasn't doing a good job with the kids.
Day 2 for me, feeling better. Back on the horse!
