No, you DIDN'T fail!
I just finished P1.

I started Fat Smash after consulting with my Doctor, as I was pretty confused about some of the food instructions (me and most everybody else, as it turns out!). My Doctor gave me the "go-ahead", but DID "tweak" the diet a tiny bit. Because I don't eat the beans, lentils, etc. that provide protein in P1, one of the "tweaks" she suggested was that I substitute 2 oz. of LEAN turkey or chicken during the detox phase. I tried not to do this during the first 4 days, but when I did eat some chicken on day 4, I was completely "revived". I was at peace with the fact that this is a definite "no-no", and comfortable with the fact that I probably wouldn't get that quick jump start to my weight loss. But, lo and behold, my energy was kicked up, my work out intensity increased, I started feeling alot better, and I lost 9 pounds (more than I thought I would).
As a result, I think I'm going to keep doing what I'm doing, just adding a little bit more variety for breakfast (I never thought I'd be so happy to see corn flakes!).
Keep it up! I just found the Fat Smash group, and I'd like to check in regularly!
