Sounds like all the symptoms you are describing as you possibly having a small intestine bacterial overgrowth (SIBO). My GI said that alot of us who have had multiple resections are more prone to getting SIBO. I did a quick 10 day course of antibiotics along with a stronger probiotic and it really helped alot.
My symptoms were alot of gas and bloating especially right after a meal. I would get soooo bloated that even my sides hurt and the gas, oh my gosh, I just couldn't get relief. I believe you have an appt soon with your GI, you might discuss your symptoms with him and the possibility of a SIBO. I thought for sure I was flaring and it turned out to be bacterial overgrowth.
As for relief for the gas, your tricks are basically my tricks. I have heard that charcoal capsules help, but all they did was give me bad constipation. Good luck!
