Hey Betta, have you read the Maker's Diet yet? What food couldn't you handle? Did you slowly transition or start the 40 day program? The program is too strict for me. I had to do it backwards, being more leniant at first and then changing as I became comfortable.
If you do anything for your health, make it checking out Weston A Price's site. It has so much valuable nutrition info, even if you aren't on the MD.
I wish I could send you a bottle of Primal Defense. That one bottle would change you digestion and your life!
