I am just one day ahead of you> I started in Sat, so I am finishing up day 4 right now. If you have made it through the first few days, you should be fine. I have done a few Master-Cleanse fast (21 days, and a couple 10 days). I always find the first couple days the hardest. I also will be doing 10 days, I think I will do 10 maybe +/- 1 or 2 days.
