Two years huh? Hmm...well I know that you'll have to taper off with a continually-waning dose for awhile. As far as the IBS...I used to have terrible IBS, and I tried several things such as Hyoscamine, Bentyl, Donnatoll, until it finally just sorta went away. I've heard mixed reports about antidepressants and IBS, but I don't know exactly what the interaction is. Fortunately there has been a TON of research into this field in the last couple years, and theres lots of treatments for IBS. You should ask your MD about
Zelnorm, as well as Bellamine-S,
Librax, Bentyl, Levsin...those work great.
Hope this helps.
