Everyone responds differently during the cleanse depending on their personal health situation. It's actually quite normal to feel a bit "icky" on the cleanse because toxins are eliminated from cells that then enter the bloodstream. This is a good thing because it provides your body the chance to eliminate them but make you feel nauseous or even lethargic at times. In addition, bacterial, yeast and other microorganism populations are re balanced in the intestines which can lead to what is called the Herxheimer Effect, but it usually doesn't last long and once the toxins are cleared, most people report feeling AMAZING and having LOTS OF ENERGY!
