I'm starting another Master-Cleanse fast today. I just finished a 12 Day one on Friday but realize now that I wasn't fully cleansed and want to lose some weight so I'm going to go for the full 40 days. I tried to start with a salt water flush yesterday but that back fired. You can read my post on the Master Cleanse Support Forum for the story. Happy fasting! The longest I ever fasted was this past 12 days and felt great! I don't know why I planned on stopping, I guess I feared losing too much weight (i'm average, but could be slimmer). I want to go 40! I hope your fast is going well. What kind are you doing? How long?
