Jeff,
Within one year after takedown I was experiencing frequent and urgent bowel movements in the one hour after eating meals. I was diagnosed with spasmodic pouch. I was prescribed bentyl, then levsin, then donnatal, all anti-spasmodics and all of which work well. With bentyl and levsin I experienced a large degree of feeling loopy/lightheaded, less so with donnatal. You take a pill 30-45 minutes before eating a meal and the spasmodic pouch issue is solved. Completely solved. The only issue then is the degree of the side effects from the meds as discussed above.
I read posts on this board and I think a lot of people have spasmodic pouch after takedown and don't realize it. They try to throw imodium after the problem and imodium is not really effective as it does not control motility as an anti-spasmodic does.
This issue died down for me as I got farther out from takedown. I only need to take donnatal very occasionally these days. A lot of people on the board expect INSTANT results and especially on an issue like excessive motility it took many months or maybe a year before I noticed a palpable change towards normalcy when I ate meals. Try these anti-spasmodic meds and be patient because the motility issue may change over the course of time.
