There's a few older thread on this but things change in the wonderful world of colonoscopies, especially when it comes to preps where you don't have to drink a ton of stuff. I'm getting my 5 year one in November. The last time I used a kit called Lo So Prep which is low salt magnesium , dulcolax tablets and dulcolax suppository. My doc said it worked great so I'm trying to locate one. She said also Suprep, which is also an easy prep but I've read where some people say it didn't work well. With my IBS-C I have concerns. In fact with the Lo So Prep it took longer for the dulcolax tablets to work. I was up pretty late waiting for them to work. I have read where big Gi Centers let people make their own kit with magnesium citrate liquid and dulcolax. I'm tempted to do that. Any ideas? I did see where Freddd talked about low potassium and @ahmo suggested foot baths so that's a good idea. Please tag me.
