Yes - definitely look into reflux. I agree with angeleventide.
I have been taking aloe vera (juice or softgels) which have helped a lot with my reflux/irritation. Don't be stingy on the dosage. I still do get the heartbeating - but aloe vera has cut it down. You could also try regular old antacids.
A follow up question would be - why the irritation/reflux is happening? Food intolerance, gluten intolerance, candida, parasites, hiatal hernia? Could be any of these or something else.
