As myroro said it was not a failure. It works in the first 30minutes even if you vomit. When I started I read all the flushes at the top of the page under cleanse. Dr.Kelley suggested to take a glass of water with Alka Seltzer GOLD (no aspirin) to bed. I sipped through the night against nausea. After several flushes I realized I never used it so I stopped it.
