I think you need to try to reduce your gas. Hopefully the flagyl will help close up that fistula soon.
I suggest the days you're in OR or other confined areas, try eliminating everything gassy, like dairy, hard to digest meats and proteins, broccoli, cauliflower, etc. Also, imodium or an anti-gas (gas-x?) might help those days. Have you tried probiotics yet? I take Garden of Life Primal Defense and they help with bloating and gas. Just go slow with probiotics, as they can cause detox effects.
I'm not sure what else to recommend, but maybe your GI will have more suggestions. I hope you will solve this problem soon and good luck with your studies!
