1st cleanse = April, 2004
2nd cleanse = February, 2005
I think it really depends on how toxic you feel. I reaped the benefits of the first cleanse for many many months until I resumed poor eating habits in December (ahhh...the holidays). Let me tell you, it only took me 2 months to feel clogged, bloated, and fat! I went a good 6 months feeling fantastic. If I learned anything - after this cleans it's no processed Sugar or carbs for this gal!
