Last night, I took my final two capsules a month long, natural colon cleanse and organ detoxification regimen from Renew Life. It involved taking two tablets in the mornings thirty minutes before breakfast and two other capsules three hours after supper. There were some other recommendations like drink more water, eliminate dairy, wheat, and sugar while adding some strange grains, exercising, etc., but I wasn't about to give up eating cheese.
Over all, I think it went quite smoothly. I recommend it - it won't hurt at the very least as it is quite gentle. I didn't feel hypervitalized, but I did feel better knowing toxins were leaving my body more efficiently. Can't beat the price either - only $35.
