When my hsuband was ill and had to take so many heavy pain killers, the doctor suggested something we found at a good health food store. It is in a white bottle, green print and has a colon on it, it is called "Super Colon Cleanse". While it sounds awful, it isn't, will not act as a laxative, will not give you gas or the runs but WILL clean you out with some good soft movements! He was in bad shape so he followed the directions on the bottle, along with lots of water I drink daily, I take about three of the caps at night once a week. Works for me and tends to also make things normal for awhile. This is all herbal.....great stuff and we tried EVERYTHING for him.
