I like the feeling of being stuffed, however it comes; and even more, the feeling of release from an enema that flushes it all away. And if the first 'plug' of shit stretches my anus nicely, that adds to the pleasure.
So, I have done this. Find an Immodium generic (loperamide 2mg). The cheapest one I know is called Prodium, and we keep a jar of five hundred tablets for my wife's bowel problem. They're quite cheap, ExPat: about 50 SA cents a tablet. Now find out how many you have to take to stop your bowel from emptying. The drug has a ten hour half life in your system. They don't recommend more than eight tablets a day, but you must space them regularly to get it to work right. Start with one every six hours. If it doesn't stop you from shitting, increase the dose until it does. Don't take more tablets at once, just reduce the interval between tablets.
I'm quite resistant to the stuff. I have to take ten a day to bring my colon to a a halt; but I don't recommend this.
After a good clean out enema, I leave two days and then start taking the tablets. It will be about 8-10 days before I begin to feel stuffed, and I can usually feel a hard mass of shit through the wall of my abdomen. My record was 15 days before the next enema. Is that constipated, or what?
The drug does have side effects for me. I'm OK for a week, but after that I get very weary and paradoxically it becomes hard to sleep. However, the enema expulsion is humungous - a rock pile! It will almost always block a toilet if expelled there, for the first turd can be up to two and half inches thick and easily five inches long.
I have an old fashioned chamber pot to receive the load; and in this I can break up the shit into manageable bits.
