I dont often get constipation, but a few times i had, post surgery due to pain meds. My favorite to clean me out is to OD on vitamin C. A massive dose, like 9 grams at once, will clean you out. you will have diarhea for an hour or so.... works great. No danger, you get your fill of the C your body needs, and your digestive tract flushes out all the excess....ta da.

yes, its impossible to hurt yourself with vitamin c. In fact, you can actually absorb alot more than that intravenously with no problems....but orally, it helps you purge because your digestive tract can only digest so much of it at a time.

nope, no cramping. Just liquid passing.
