I agree with Michael, but I feel like a cheat is good maybe once a week, maybe that's because I'm a carboholic.
What's with May 15th?
There may be a connection with relationships. You may have to look into that honestly. Are you getting comfortable and just eating more or is it something else?
As far as people staring at you at the gym... I think it's normal to feel like that at first. That's just something you'll have to get over. Once you're there and get to know people you'll realize that they were never staring, they are too involved in what they are doing. Oh and the ones that are being stared at, are probably wanting the attention.
