I have played around with my supplements and diet and found this regimen works best to keep loose stools in check:
6am - 4 psyllium husk capsules (2.2g fiber)
9am - 1 Caltrate 600 Plus Chewable
1pm - 4 psyllium husk capsules
7pm - 1 Caltrate 600 Plus Chewable
8pm - 4 psyllium husk capsules
Bedtime - 1 500mg Vitamin C and a probiotic
Things are best if I avoid a lot of insoluble fiber, have my morning smoothie, have fresh fruit and sweet potatoes or black beans throughout the day. Other than that, I haven't been too strict the last 2 weeks.
