A good GI doctor recommended another solution to me. I used it for years. It doesn't involve any medicine so it doesn't have side effects.
His recommendation was to take large doses of psyllium powder
. Don't misunderstand me. In regular size doses, psyllium acts as a lubricant for the colon and will clear it out. BUTT in large doses it actually stabilizes colonic motion. The dose he recommended is about a quarter - cup to a third - cup at at time.
This is how you take it. You prepare a 12-ounce drinking glass about 2/3 full of drinking water. In a little measuring cup have ready the dose of psyllium powder. Have a stirring spoon ready. Then with quick motions you dump the psyllium powder into the water and quickly stir it. Get the psyllium wet but don't hesitate. HOLD YOUR BREATH. Then drink it quickly. Rinse the glass out with a little water to consume the dregs.
The way that it acts is that it provides 1. a lot of fiber bulk to the intestine, which helps it to not be ADHD (I know that this is an invalid comparison). The point is that the intestine is churning like a washing machine and it's not good for it to injure itself churning too much. 2. It tends to form a gel inside the intestine so that the contents stick together forming a workable lump. 3. It keeps the intestine from having this food become a mechanical irritant as it works inside like the action of a washing machine. 4. When the material is passed as fecal matter, it is kept soft so that it doesn't injure the anal opening or hemerrhoids.
Advice: Don't buy the kind with a lot of sugar in it. The sugar is not good for you. I trained myself to just take it raw without any sweeteners. The psyllium fiber itself is not capable of being absorbed by the intestine so that it is essentially nonnutritive.
I buy the stuff at a health food store. They order it in large quantities which gets the cost way down.
