Blackdragon, I do hope you are feeling better by now. Still, this info may be helpful to others.
I have successfully overcome IBS without medication. My doc had me do a test for gulten allergy. Because the antibodies for gluten/casein are produced in the intestines we tested that way. Test showed I'm allergic to gluten. Been off gluten since May. It's been 3 and a half months of stomachache-free living! Yippee hurray!
May this be the end of a decade of severe stomach pains, etc.
If you want more info, feel free to pm or post here.
Take care!
