gaining guilt

Today I had planned out what I was going to eat when I went to my Mom's. I decided I would have 2 pieces of pizza, but my husband and Mom had some of my favorite Chinese food. I was doing well...until I walked by an egg roll. I just could not turn it away. I tried, but I caved. Then I felt so guilty that I came home and ran 2 miles in my house. I burned 200 calories and I am hoping that egg roll wasn't anymore calories then that. I don't know if there has ever been a time in my life where I would have cared so much that I cheated, that I would need to come home and try to work that off. I hope this is finally my time that I am serious enough about this weight loss thing. Time will tell, but someone told me that it takes 28 days to make something a habit and I am on day 25 of this. 3 more days!!!
I ordered a heart rate monitor watch. I hope it is a good one.
It's ugly, but I won't care as long as it helps me track my calories.
