My solution for cramping is levsin, which does a good job of stopping everything for a while.
though I take Imodium 3x/daily, I see it’s value as slowing things down long enough to have less caustic/acidic BMs .
when I experience IPS ( I am former IBS sufferer), one levsin under the tongue works in about 5-10 minutes and I get relief.
BTW, I average 6 BMs per day, so my feeling is 6-8 is not excessive, but 3-4 per day is impressive to me.
