Does anyone believe in Colon Cleansing?

I know a little bit about colon cleansing and the facts on colon cleansing and what it does to improve your health, but has anyone ever done a colon cleanse and if so, what is best product and most affordable one out there that works? I am just curious to if a clogged colon is responsible for all sorts of problems like foggy memory, lack of energy, irregular bowels and not having a bowel movement everyday, lack of concentration, mood swings, as well as a pop belly when you aren’t exactly that much overweight. Those symptoms represent me and I was wondering if doing a colon cleanse regimen would make me feel like a whole new person and give me energy and strength to go work out in a gym and build up my muscles. Any thoughts or suggestions would be greatly appreciated.
