My husband has Crohn's and he pretty much needs a bathroom before every ride. He takes a therapy called Remicade and immediately after his treatment it is much worse, when it is near treatment it gets bad again but he usually ends up constipated so urge but no relief.

His GI doctor has recommended Align, gave him a prescription to ease spasms, of course my husband doesn't remember to take them. A nutritionist or a good GI doctor might be worth a visit if you would like more relief. Bottom line, you are far from alone.
