I'm shooting for 21 -- looking at 10 days to start and will see how it goes. I'm on cleanse #2 as well (after a successful cleanse in April, 2004).
My hubby doesn't cleanse, but oh boy does he help me in other ways. He does all the cooking and makes dinners/lunch for my son. All I have to do is pour him a bowl of cereal in the morn!
