I have been suffering from pretty much the same thing for the past couple of
years. I choke up the clear stuff, eating
seems to make it worse, etc. I've been to dozens of
doctors and have what seems like very few answers. I have, however been diagnosed with a hiatal hernia and esophageal dysmotility (my esophagus doesn't work very well) They tested me for acid, but that was minimal acid coming up, so no reflux.
