I have severe urgency issue since a surgery years ago. The first few years all my BM's were very loose. The doc recommended I use a bulk producing fiber supplement to firm thing up. I experimented and found if I have 3 or 4 large doses of Metamucil everyday I have firmer, well formed BM's. It doesn't help the urgency any and I have more frequency and larger volume. For some social situations (like flying) i will take loperamide and it has a constipating effect. When it wears off I usually have several enormous BM's. They literally fill the diaper completely, front to back. An average person will produce around a pound of poop a day, give or take. My estimate for a mega load is probably around 5 pounds. Yea, I know. Gross.
