I feel for you. I remember hearing, in a drug-filled haze, the word “normal” when I was waking up from my colonoscopy. I wanted to cry. I have severe symptoms and nothing has given me much relief. My regular doctor has been treating it (or trying to) for a few months, but I think I’ll go back to the gastro to get medicine that only he can prescribe (I can’t think of the name right now, but it’s on the Mayo Clinic site about IBS). Lomodal has helped a bit. Have you tried it? Also, you could try Marinol for the nausea, though it makes you pretty spacy (or it did me–my doc won’t give it to me anymore.) Good luck to you! let me know if you find something that works!
