Hi Lisa,
I was the same way in the morning Iwas like "I feel horrible I'm going to stop this" by noon not too bad and by the end of work thinking about that glass of wine and stopping by the store for a bottle or two and 2 of those mini vodka bottles.
I hate it - hate being tied to the wine store - hate trying to find a place to trow away my mini vodka bottles before I walk into the gym to pick up one of my kids.
Stay strong - maybe wriote yourself a letter in the morning and read it before you leave work...
Stay strong.
