NinjaNurse - I know exactly how you feel. I have gone through periods of anger, frustration, depression, and extreme joy since beginning IP. I have felt resentment that I can't have the goodies everyone else is having. While my family was here for a week I made great food and desserts for them. I couldn't have cocktails or the same food. I stayed 100% OP and there were a few moments that I thought it really sucked. This happens periodically. I just try to keep focused on how much better I am feeling, and try to imagine that this is a short period out of my life to get healthy and affect my future. I love wearing smaller clothes and feeling more attractive to my DH. I know that for a few moments of enjoyment it just isn't worth it to me.
I think someone has a quote on their signature that says, "nothing tastes as good as skinny feels". I tell myself that all the time. I also do as a lot of others have stated, and mix it up in the recipe department when I am feeling this way. Today I am making a roast in the slow cooker with onions and mushrooms and will have sauteed asparagus! The other day we grilled steaks and had roasted cauliflower. Not too shabby for dinner.
Hang in there! There is a rhubarb crisp recipe made with the oatmeal packet that everyone raves about. Make yourself some dessert and maybe that will help.
Good luck.
