I would experiment with adding Metamucil. If you have the powder, mix it up with just a little water to make a sludge, and down it-I like to take it just before meals, or possibly before bed. I used rouse the powder, then I switched to the wafers-ate one before meals, or now Intake the capsules-the trick it to just take the fiber, but not the extra water as directed, because you want the fiber to sop up the water already in your system.
It may help thicken the stool and slow down the frequency. I find when I have a lot of BMs ai get so sore down there that it seems to signal a trigger to evacuate more often, so it is a negative spiral.
I hope you find relief soon.
