serotonin cure for fecal odor

Low Serotonin seems to be the reason why we have fecal odor because it is responsible for the fact that our digestive nerves don't work as well as they used to. And people that have had fecal odor here in the past have reported good results after taking Serotonin-boosting meds. I also heard on ITV from a guy that was selling a Colon Cleanse formula that sugar(y) stuffs like juice cause the walls of the colon to secrete mucous to absorb/nullify the acid produced by the juice. As a result, foods start getting attached to the walls of the colon resulting in incomplete digestion. I stopped drinking water over 2 years ago and drink nothing but juice now. And I have fecal odor. I would like to know what you guys have being drinking before your fecal odor - Juice or Water or both (the percentage of each)?
