I am about to start the Master Cleanse for the first time - bought the books and supplies but have one more question. Can I use some herbal teas while doing the Master Cleanse? To be specific, I have two Yogi teas that seem like they would be beneficial to helping me detox and keep my metabolism up and my appetite down (important to me since I have about 50 pounds to lose) - one of the Yogi teas is called "Detox" (with herbs to support liver and kidney function), the second is called "Fasting" (with herbs to support metabolism, elimination, appetite, and liver). Can I use these teas once or twice a day during the cleanse to help me through - or will they impede the results of the Master Cleanse? Thanks so much for your help!
