I am on my fourth Master-Cleanse and for me each time has been easier. The first two times I had bad headaches, nausea, aches, dizziness the first 3 days. Then it seemed to ease off. The third time I had more nausea but very little headache. This time I am on day 3 and there hasn't been a sign of any of these symptoms, if anything, I felt better right away. I do have the chewing craving the first 3-4 days but no hunger at all. I am a vegetarian otherwise. I'll be trying to stay vegan after this time. One thing is, I haven't been able to go beyond day 23, it just seems that it feels enough, it's hard to describe.
I appreciate the advice about molasses, there is also mineral water in Whole Foods, one type is "Fiji" artesian that has calcium, magnesium and potassium.
I didn't have this forum then, I found it and it is very inspiring and helpful to find other people doing it.
