My doc said stop immodium 24 hours before but I’m sure every doc is different. I can’t imagine going 5 days without it if your having a lot of symptoms. If it’s just a routine pouchoscopy then maybe you don’t take that many immodium and maybe it’s not a problem.
i did the magnesium citrate bottle the night before and the enemy the morning of the procedure. The enema the morning of was a little useless since nothing more came out. I see why they do it, but maybe your doc doesn’t see it as necessary. They all have their reasons. I wouldn’t worry too much. Like Scott says, they suck the residue out anyhow so as long as you do your best.
good luck!
