I'm guessing that your cleansing pill contains a fair amount of dandelion root. I am not a doctor but it has been my experience that dandelion root is good for liver detoxification but not so good for colon cleansing. You may be cleansing to quickly and that could cause the mucus you are describing. Mucus is also indicative of candida overgrowth which may be the cause or a contributing factor to your acid reflux problem. While the mucus discharge is not "normal" in colon cleansing, it is not all that uncommon.

I suggest that you cut your colon cleansing pill dose in half for the next few days and then gradually increase back to the recommended amount. If your energy doesn't return after you have gradually increased back to the recommended dosage I would consider discontinuing this cleanse.

There are plenty of gentle and effective colon cleansing programs available both online and in retail health food stores. Why worry or suffer?

Please feel free to ask me any futher questions.

Good luck on your journey to good health.

Namaste.
