I used to be a WI day binger...after group it would be something of the sweet variety! I still have a treat after class, but I've been pretty strict with myself since I started...previously that binge would have gone from Wednesday to Sunday, but now I have one thing (sometimes more) and when I'm done, I'm done.
The biggest change I've noticed is that I can't even stomach a majority of the stuff I used to crave so badly. The last choccie bar I had as a treat was a snickers bar, and I had to give half away...nothing like the old me at all! Also, I'm more mindful of the portions - I find it much easier to have a decent week if I get my treat day out of the way on a Wednesday night (unless I have something at the weekend).
My proviso is, I eat my SW meal first and have my treat as a dessert. Also, I plan what I'm craving, and buy JUST that, which used to be a feat in itself! I was the queen of the evil "multipacks".
