I generally cannot empty my pouch completely if I am constipated. 1tsp pysillum husk in morning and evening keep it tight enough to hold easy and loose enough to help it pass. I couldnt do imodium in past as it gets me heavily constipated and I cant clear the pouch without applying too much pressure. The general rule I've had is if I pass gas and the end of a bm my pouch feels empty , if the gas gets stuck in I may soon end up in the toilet again.
