I am on day 2 of the 14 QT Burn & Cleanse. I am NOT experiencing any of the negative side effects mentioned by other users. I did feel an increase in energy and did use the restroom frequently, which I expected and don’t mind…means its working. I slept through the night just fine and am feeling pretty normal. I’m healthy, but after a recent surgery I’ve put on about 15 lbs. I am a morning coffee drinker, but for the duration of the next two weeks, I will NOT drink coffee since the pills already contain caffeine — just a lil’ common sense. I am also eating a yogurt/small amount of fruit with the pills to avoid any nausea. Drink plenty of water! I think if you read the enclosed booklet, apply some common sense and pay close attention to your body and your personal needs, this product can help.
