I did The Master Cleanse for 10 days about 6 months ago and I can tell you it really works. I felt great! I am now living in an extremely remote place and tried to do this again but failed after the first couple of days, but I think it was because I wasn't using the prescribed ingredients. I couldn't find Senna tea, so I used laxative pills. I had sea salt, but not the right kind, and I also didn't have Grade B organic maple syrup, just regular Grade A. I am wanting to try this again, so this time I'm ordering this kit, which seems like a fair price since it includes everything you need. Only thing I have to say about this kit is that you could probably use more like 80 oz. of syrup, not 64.
Overall, give this cleanse a fair shot and I promise you will not be disappointed!
