I slipped this weekend

I have been doing well with the food intake and such but that wine just does me in. My girlfriend came over and we drank 2 bottles (she had just done a washington state wine tour) between us and that makes me mad at myself. All that sugar and useless calories and I feel like crap the next day. I have been doing better cutting out the wine but obviously I need to work harder. I can do this! I want to feel better!
