YES, although my stomach didn't start acting up until I started Phase II five days ago. I think it might be settling down now.

During Phase I, I was cranky if I didn't get dinner on time, and my face was really oily. But on the positive side, my energy is up, and I haven't once had a stomachache from being overfull of bad food! It's wierd because nothing I'm eating is really new, and I didn't have digestion problems with it before, so I think it must be the artificial sweeteners, which I have NEVER used in the past. I'm trying to keep those to a bare minimum now.
