Backtome, I know exactly how you feel. I've been struggling through the midway point for a while and I've been stalled on weightloss again for the last two weeks. But I have found some things that helped. Last time I was on a really bad eating kick I started carrying a piece of paper in my pocket that asked two questions:
"Why do I want to eat this?"
"How will eating this make me feel?"
Every time I went for the ice cream I tried to ask myself these two questions. To be honest, it worked okay, but when stressed I still had the ice cream. Next time I think I would add one more question.
"What else can I eat that would be better for me?"
Also consider making a list of all the good reasons why you want to lose weight. Keep it in your pocket, hang it in the kitchen, tape it to the cookie jar. It will almost be as good as having JayEll around to yell at you
