Try drinking more water. If I notice burning in my throat, then I know I didn't drink enough water. Same might be for the stomach. I hear from a lot of my friends that are on the cleanse that if they don't drink enough water they too feel burning. Hang in there, it is so worth it in the end. I am on my 4th Humaworm cleanse and on day 12 and I started feeling rubber legs again and all my energy was zapped again. Today I seen what was giving me the rubber legs and the die off syndrome. Flukes! Once the dead ones are out, then all my energy and then some returns again. Donna
