So with the Schulze you ARE having BMs. That is good news. That means that you DO have peristaltic action. Your colon is NOT paralyzed. It has merely become "lazy" from an overuse of laxatives, enemas & colonics. The first thing that you need to do is normalize your bowel function. You need to eat lots of watery fruits & vegetables, raw. Drink raw juices. Eliminate dairy from your diet. Dairy is mucous forming & constipating. Drink LOTS of pure water with Sea Salt . And, be patient on the toilet. If you have to sit for an hour,do so. One thing that would help is to find something to put your feet on so you are basically in a squatting position. This is the natural posture for defecation. Don't stress, and don't go digging. Your body DOES know what to do.
There are a lot of people here more knowledgable than I am. I don't know what supplements would be good for you at this time. I would say to discontinue supplements at this time. There is a good chance that you will need some help rebuilding intestinal flora.
