Thanks MaineWill..I hope your gut feel is correct

You are right about the alocohol part..I had this affair with Cask strength whiskies and an eye for good scotch. Of course I do not exactly drink them neat, but still use very little water occasionally.. Luckily I never had any issue with stopping..no withdrawal symptoms etc. It is just that I never felt I was going over the limit..Anyway, not drinking for the last 2 weeks or more and haven't had even the faintest urge to drink.. I feel fresh, that bad breath that refused go away no matter what I did to my teeth is gone and I am getting more quality sleep..I intend to stay away from alcohol for a few months and even if I drink later, I do not intend to drink more than few drams during the weekends.
Coming to the sore throat.. I went to another ENT and he says it look mostly a case of LP reflux. He did not scope me either, just indirect one with mirror. There seem to be swelling and he is of the opinion it is better to have an Endoscopy, if I need it, after the swelling subside because upper endoscopy would be difficult with the swelling, he felt.
I have been prescribed Nexium 40 mg once a day along with an antihistamine. It has been two days since and I feel throat is improving. May be I am relieved considerably, the appetite is back too..I am told to consult the doc after two weeks.
I realize I might have to live with reflux now and am taking steps to correct my life style. In the hindsight the worse thing I did must be to eat just before I slept, just after I finished drinking alcohol. Nowadays I eat at least 2-3 hours before I sleep. I reduced or stopped all greasy food. Fruits and vegetables are back. I sleep with my upper torso up. Taking a few light meals in between. The burping and gas seem to be gone since Nexium or it could be the cumulative effect of all the changes in habits.
I intend to do an upper endoscopy sometime next month when my prescription for Nexium finish or if the swelling do not subside in 2 weeks.
Thanks for this wonderful bunch of brave people.
