Bowel movements are habit forming. There is no one-size fits all. Everybody needs something to be put in at the top in order for the coming out at the bottom to happen. Ideally it is the putting in of nutritious stuff on top that causes the regular coming out at the bottom but relatively few people, myself included, faithfully do every day what is ideal, thus the wide range of aids that people use to help this necessary habit. Ive been using IF number 1 for over 5 years and have been at a point for a couple years where one a day at evening meal is enough to maintain a once a day BM.
Bowel movements should be a daily habit, everyday. What was you taking prior to starting the Schulze formula? Whatever it was, that too was habit forming and it must not have allowed you to have formed whatever habit you desire if it led you to try the Schulze formula.
