This is my first time. I haven't seen too many changes yet. My skin does seem to be softer tho. Haven't had too many ill side effects either. Had a headache the day before yesterday for the whole day, not sure why. It's gone now, and I feel just great! Not hungry at all but miss eating, ya know? I'm going to try to last as long as I can. Maybe 40 days. We'll see. I really want to change the way I eat. Not give up all the things I like but want to make better choices most of the time.
