Do not eat anything for at least 3 hours before you come for your Colonic Session. You will feel much more comfortable during colon cleansing with an empty stomach. You will have less cramps, feel less pressure inside and more water will be able to enter much deeper and cleanse more when you have an empty stomach. Your colon hydrotherapy will also be more comfortable if you avoid the colon irritating foods listed above. Those foods produce inflammation and gas in the colon.
