Tomorrow it begins!

M and I are starting the "50 million pound challenge" tomorrow. I said my goal is to lose 20 pounds, but now I'm wondering if that is realistic. Maybe 15. Or 10. Ugh. I need to go grocery shopping today to get the food that we're supposed to eat. The website is pretty cool - they give you weekly meal plans complete with shopping lists. I wonder if I can do this. I have been hating my body lately. I feel so flubbery and fat. It doesn't help that my aerobics class doesn't meet this week due to spring break. Grrrr.
