My last pouch check called for a prep of magnesium citrate. Always before my doctor recommended Miralax mixed with Gatorade (not red). They followed that with laxatives taken with gas x. Before the prep, I was on a liquid diet. Both seemed to work fine, the magnesium citrate better, but personally, the taste leaves much to be desired
Every GI is different. I'd ask your doctor what he/she recommends. We definitely don't have to take the prep full colon people do. From what I hear, drinking that poison is worse
None of these preps are pleasant, but if they give the doctor a clear picture of the pouch they're worth it. There is nothing like peace of mind knowing what is going on inside.
Thinking of you!
