I have found Walmucil (Walgreens brand- does not have Aspartane in it) helps me greatly keeping stools from being liquid and bulks them up which reduces frequency. Also, without it 3x day with meals, my output is very acidic and causes serious butt burn. I'm 2.5 years out and do need to take Lomotil to slow things and Colestipol for acid. I also find I sometimes need more carbs to bulk things up though others have eliminated those for pouchitis/gas issues. Good luck!
