The more water the better, it gets things moving. I am so shocked at the lack of basic information out there. I have IBS yet so do many of my clients and one of the biggest relievers is to drink about 1/2 - 1 gallon of water a day. Also, have you tried psyllium ? A natural fiber that cleans you out. I loved Citracel before finding Primal Defense.....thats by Garden of Life and it's the best so far. Take a few scoops before bed (or the capsules ) and you will be cleaned out by morning with no bloating or cramping. I know how you feel about grabbing a laxative, and that cleand out feeling is great, yet do it naturally, eat lots of well cooked vegetables, dont' eat dairy or wheat products and keep your meals really small yet frequent. Try some of those things above and write back.
