How about this: a large bowl of Uncle Sam cereal moistened with the yogurt drink of your choice (not plain milk, which is binding), a glass of prune juice, and a mug of black coffee with artificial sweetener. If that fails to get things moving, you’re gonna need a trained medical professional.
Also remember that high-fiber foods need water to really do their thing. Too much fiber and too little water in the diet causes what we might call a colonic traffic jam.
Thai/Filipino cuisine made with coconut milk. I love a good curry, but since it’s made with coconut milk, I can normally expect a trip to the lavatory.
Papa John’s Pizza. At least for some of us.
The Beast: Triple Leaf Teas Herbal Laxative tea. Never tried it myself, this is from other testimonials. Although, I don’t know if I’d describe it as “readily available”.
Slight hijack in regards to prunes. Prunes have such a “shitty” reputation that they are nowadays not sold as “prunes”, but rather “dried plums”. Of course, prunes were and always will be dried plums, but most packaging today avoids the word “prune”.
PS, sorry for all the "s. 
Oddly enough, if I drink a pint of Tropicana Orange Juice, I’m off to the races not to soon after.
if you have any degree of lactose sensativity, milk and/or ice cream would work.
“P” fruits are good, but so are dried fruits in general (raisins always did it for me)
whatever you chose to eat, be sure to drink lots of water as well, because the food could have the opposite effect on your system and do more than just “unclog” you, and you wouldn’t want to become dehydrated.
Not for everyone. My mom bought some of those and I had a few. No laxative effect but it built up a huuuuge amount of gas that would not leave. Oh god, that hurt so bad.
Oh, no, you have to eat the whole bag.
Another good laxative food - onion soup. The super-nice thing about that is it comes out identical to how it went in.
Or it just doesn’t act as a laxative for everyone. It says “may cause a laxative effect”, not “will”.
[sub]I mean, take that “few” there with a grain of salt, sheesh. ;)[/sub]
For me, Wheat Chex.
About this Colon Blow business (and the various charcoal/fast schemes I’ve heard of): are you supposed to clean out your intestine that throughly? Isn’t there a system built up in there that works the way it should??
This may be an urban myth, but I have heard the a couple drops of Visine in a drink will give someone the trots.
ooooo never again !!!
I was told to do the whole liquiprep kit [the bottle of mag citrate AND the 4 little red pills of doom.] I was crapping my brains out for a week =(
Never mind. I checked on Snopes and this is actually bad stuff! Link.
Actually, I did this shortly after I joined, but I can’t find it; it might have fallen victim to Our Winter of Missed Content. Highlights: “Two words – rope-like.”
Vitamin C, in general.
TGI Fridays
Coffee and apples. Tea and plums.
-Warm apples; as in apple cobbler or apple-brown-betty
-Popeye’s spicy chicken.
-CrackerJack and LOTS of liquids.
-Corn.
When our daughter was very young, her grandparents had standing orders to have some kind of melon on hand when we visited. She tended to get constipated when she was away from home, and melon (watermelon, honeydew melon, catawba melon, canteloupe, or anything) seemed to cure the problem in about six hours.
It helps that she doesn’t get melon fruit very often, so even now that she’s 14yo, she thinks that getting honeydew melon or canteloupe at Grandma’s house is a treat.
For myself, while I realize that coffee is not on any kind of list as a recognizable purgative, my morning cup of coffee is really all I need most of the time.
