I too plan on starting my third Master-Cleanse tomorrow; not sure how long I'll go, at least two weeks, I hope. My previous MCs were each only 10 days long, so I have no experience with Master-Cleanse after that length of time. It seems, though, that everyone's experience is unique, so knowing how someone else felt during a certain phase of Master-Cleanse does not necessarily mean you will feel that way. Anyhow, good luck with Day 1 tomorrow. I'll be right there with you!
