How do you know that you are done?

I've been doing the cleanse for 6 days now and I really have been feeling great! I've lost 12 pounds and I'm really not eliminating anything anymore eventhough I'm drinking the tea in the evening and morning. I have not had any cravings nor have I really been hungry. I'm thinking that maybe my body wasn't as toxic as I thought it was. Do you think that going 7 days is long enough?
