Thank you for the advice FurballsMom
I haven't heard the names of these medications you mentioned. I take an antispasmodic called Bentyl. The generic name is Dicylcomine. As for which medication is best, I think that really varies and depends on the individual. There is a newer medication called Hyocyamine that is a sublingual medication. I tried it, but I didn't think it was effective for me at all. The drawback with the Bentyl is that it's sedating and it shouldn't be used long-term non-stop. So, I only use it when I'm experiencing a painful flareup.
