I had the feeling I couldn’t poop for some reason for two days, I also had some sickness from being exposed to too much AC (the doctor said), the doctor gave me medicine against the other stuff which works wonderfully. But my stomach hurt a lot so I ordered a 1 liter bottle of prune juice because I heard it helps against constipation.
Once it arrived I drank the whole bottle at once just to be sure, because I heard it’s a natural mild laxative and my stomach hurt so much.
And it worked very well, after 2 hours I was running to the toilet and getting rid of whatever was stuck in there. It worked very well, my stomach stopped hurting after one more hour, wonderful!
But I didn’t need to drink the whole bottle, I’m stuck on the toilet the whole afternoon now because as soon as I get out, 2 minutes later I need to run back in, so it’s just easier to stay on it.
I think like a cup or two might have been enough.
I would say this also goes for dried prunes, once I ate most of a bag and got a similar experience, it just takes a bit longer before you run to the toilet.
Dried or fresh cherries will also produce the effect in sufficient quantity. Which is how I learned not to eat a bag in a sitting.
