Can I clean my colon with an douche.......?

Continue with the raisin bran and juice and make sure you drink plenty of fluids. Have a piece of fruit if you want a sweet snack. Make sure also to keep active. Do not do an douche. It can be very dangerous, even life-threatening. Talk with a pharmacist about over-the-counter remedies for constipation. There is not one shred of evidence that colon cleansings are heathy for you. These cleansings remove the beneficial bacteria from your colon which could result in some very serious medical conditions.
