She has bile reflux. I have also become suspicious that I have bile reflux. I think that is why I get the sour mouth after the nite. Anyway I am using xanax to help this problem . The xanax antagonizes cholecystokinin.
Cholecystokinin is a neurotransmitter which is both in the brain and the gut.
Going back to your post, of course bec i'm sitting here with a left ovarian cyst, i am thinking about your situation and just wondering, tell me K - did you ever have heartburn before you took a ppi med. Or is it just now that this has happened. I know you are thinking it was from antibiotic for the bladder infection or whatever. The meds make you hypersecrete for a while. Some folks can hypersecrete acid for a couple to a few weeks after ppi use.
