Anyone ever try the Master Cleanse?

I saw this product at Dr. Natura's site. The photos of what is supposed to come out of us is disturbing.They were also talking about parasites living in all of us & we don't know it. I could'nt stop thinking about it for weeks. I kept thinking, " I have worms in me??!!!", but was to afraid to try the product. Partly because of the price, partly because I was afraid I would get diarreah (sp?)from it (who want that)....So I told my sister about it (she'll try anything), & she did. She always has "going "problems. She said it was'nt as drastic as the site said & the only thing that was different was that she "went" a couple of times a day, which was highly unusual for her. I asked if she saw worms & she said no. I also asked if anything looked like the photos & that was a no also. I don't think she was impressed w/ it. Someone else may have a totally different result, & I would be curious to hear about their experience also.
