Any of you ex-smokers experience this?

I recently quit smoking and then got sick and started taking antibiotics. I now have this awesomely painful indigestion that is 24/7. I know that my flora is out of whack but this just makes me wanna have a smoke. Have any of you delt with this while quitting? Is there a way for me to get it on track so I can stop burping and passing amazing long winded gases that would satisfy a team of 14 year olds?! I hurt and I wanna get better damnit!
