hi james...i'm sorry about
your situation. i think what is most frustrating is not having an answer or diagnosis. how did this start for you? was it out of the blue nowhere for no apparent reason?
what do your doctors say after all your normal tests? and what tests have you had?
i'm seeing a new GI in a couple weeks just to get a second opinion because i don't like that my current doctor is blaming this on stress/anxiety.
i don't think my situation is nearly as bad as yours though. i don't have any gagging or vomiting and although i used to belch an average of 100 times per day it has gradually gotten down to maybe 25-30 per day, but i still think that is excessive (at least for me personally).
well, respond if you can.
