Every January for 6 years now, Peter Glickman with the Master Cleanse invites people to join in the first of the year 10-day cleansing. This year was a record year with 521 people joining, 119 people were brand new to the Master Cleanse!
If you are just now finding out about this and want to start in February, that's fine. You're doing yourself and your body a good thing. Continue.
I personally have done this cleanse 6 times and feel like it is a worthwhile accomplishment. Try it, you just might like it!
