I am new around here, but I feel for you..I have been coughing/choking what ever you want to call it since May..started 20 mb Aciphex about 7 weeks ago, and it is getting better each week, although not a day or night goes by sympton free. It is so frustrating. I too, have to work on the stress thing. I am not going Holy rollers on ya, but I have found that spiritual/religion what ever brings a peace and hope into the moment helps.
hang in there
