Congrats on doing 10 days! You really stopped your chronic headaches since doing the fast? That sounds great-maybe there was something in your everyday diet that could've been causing it. It's hard to try and figure out what your body is trying to tell you sometimes, I'm having a little trouble myself right now. I do have lower abdominal pains even on the cleanse, when I feel waste move through my descending colon. It doesn't happen everytime though, and I've had this problem since I was young. Kind of just sharp pains for a few moments. Also, I didn't "go" everyday on the cleanse which probably isn't good, more like every 2 days. I think it's cause my body had to sort of slow things down. I'll just have to keep reading and listening to my body :).
