I know how discouraging it is to fall off the wagon. I've done it loads of times and I'll bet that if you ask, most people would say that they have been in a similar situation. I think it's important not to beat yourself up about it. If weight loss and sticking to a plan was easy, there would not be so many of us who want to lose so badly and find it so darn difficult. Rather than feel the negative, try to turn it into something of a learning experience. Ask yourself what you think threw you off course and find ways to avoid such situations in the future, as much as possible. Set yourself up for success by planning and following through and have some go to strategies for when you're feeling weak. You can do it!
