Doctor's visit

I went to the doctor today for a follow up on my bone density. He said it was normal, and that everything looks good except for a higher level of prolactin. I don't know what he is looking for, but he had me do some bloodwork- a re-test of the prolactin and my thyroid. I used to have a low thyroid, but it went away with Synthroid. I don't take anything for it now and it's been good. The doctor's office was a pain... I was in the waiting  room for 30 minutes and then over an hour in the exam room. It's no better than the clinic I work at, and I like this doctor better. Well, kinda. I like the nurse at the clinic when he gives me my depo shot but that's it. I know this doctor is thorough. 
I keep going over my calories, even with exercise. I don't know what changed. I'm hungry and I just eat junk. I need to stop. but it's hard. I have a big breakfast like I should, and then a light lunch and baked chicken for dinner. I think I need to lighten my breakfast a bit, and just have oatmeal and coffee without the trail mix in my oatmeal. I'm over my calories today because I had a couple of small doughnuts, and I want more. I can't, though... I need to keep my calories in check. 
I'm hoping tomorrow to walk to the gym, work out, and walk home. I need to get exercise in to make me lose weight. I'm hoping to get my friend Lisa to walk and do stuff in the gym. She pushes me in a good way. I need to get these calories off!
