Good luck with your pledge!
Alcohol is fine in moderation but to excess it is very damaging to weight loss!
I used to be a big boozer with my friends but now I stick to 1-2 drinks - I try to be designated driver so I _CAN'T_ drink too much. I'm just a bit over the whole getting trashed and vomiting and hung over the next day thing now! I feel much healthier these days
It's hard to give it up and cut it down, especially when everyone else is getting drunk and you think you are missing the fun! But think about being healthy and losing weight and that should be good motivation to stay sober
