Started Slimming World so well - lost 2.5kg in my first two weeks (nearly 5lbs, really good!). Then had a really quiet weekend and after two weeks of being good and not really craving junk I've stuffed myself all weekend. I didn't even really want all the food today - I can't understand why I did it. I'm scared to weigh myself tomorrow now. What if I've put the 2.5kg back on over the weekend? What's wrong with me that I had to binge like that?
