Challenge Time

So since I start Sensotherapy next Tuesday, I decided to go ahead and get started with the healthy living plans. :) I'm going grocery shopping this Friday to stock up on healthy food. I also joined http://www.fatsecret.com/ and am participating in the challenge below. The challenge starts 3/12 and ends 5/7, so 8wks total.
