I think it's good for both cleansing and weight loss. The B&P's have been described very well in one of the earlier posts. Better than I could. I've found them helpful. I've also heard that 1/2 of the weight is gained back once you start eating. I know being a smoker/and huge coffee-fiend, I had a very painful headache the first night but since then I've felt great. No nic fits, lighter, clearer. Exercise is good, but with the BP's I've felt a little weaker so I just go for walks. I'm pretty sure the logic goes, when your tongue is bright pink again (no coating) you are done with the cleanse. Ooo! Another bonus. It's cured my insomina. I used to not be able to get to sleep until around 3 or 3:30 and now I'm in by 11P. Good luck.
