The first week I did the weekly challenge, the plan was to cut out alcohol on fast days, so 3 days a week. I never quite got that perfect, but I have only a tiny amount on fast days (a shot glass of wine - no idea why this is important to me), so it will do for now. I've kept that up even thought I've not specifically mentioned it in the weekly challenges.
The next time I did a weekly challenge, I added that I should only have one treat on non fast days. I wasn't doing terribly (sometimes I had two, but they tended to be rather small treats, and considering the binges I had been having, this was counted as success!), but then I forgot to join the weekly challenge last week and had a terrible day yesterday.
So... my challenges this week
1. no more than a shot glass of wine on fast days
2. no more than one sweet a day on non fast days
3. get to the gym at least once during the week, as well as exercising both days of the weekend.
edit to add: I'm going to stay away from weighing for awhile. If I don't like the number, I get too easily derailed. I had a gain recently, that I'm pretty sure was naproxen related water retention, but it still had me really down...
