I am at the end of my rope

At this point I don't know where is to turn to.  Previously I have posted that I suffer from Water Brash.  This started in early Nov 07.  At the time I was being treated for H. Pylori which was discovered through an endoscopy in Oct 07.  I was diagnosed with mild gastritis and mild esophgogus inflammation.  I thought "no big deal".  Boy was I wrong.

I have been suffering form Water Brash for the past three months. 

1.  I have seen my Primary Care Physician five times.  She did not know what the cause of the water brash was.

2.  I have seen two ENT's.  The second ENT said I had acid reflux and he recommended I take Prilosec and Benadryl.  These drugs did nothing for me.

3.  The GI said I now have a Hyper-Acidic condition in my stomach because the H. Pylori bacteria has been eradicated.  Therefore, my stomach is still producing excess acid to feed the eradicated H. Pylori bacteria.  I have never heard of such a thing.

4. The GI recommended I take 40 mg of Aciphex a day for six weeks.  I had to stop taking Aciphex because of sever side effects after two weeks.

5.  The GI then switched me to 80 mg of Protonix a day.  The Protonix made the water brash evenworse.

6.   I now take 80 mg of Nexium per day. So far no change in my symptoms.  I understand Nexium is very similar to Prilosec(same basic ingredients and made by the same company).  But Nexium costs much more.

I also now feel like there is something stuck in my throat, my throat feels hoarse, and at times I feel a slight burning sensation as I swallow food and after I eat. At other times I feel slight heartburn all day.

Can anyone suggest something else I can do.  I get about an hour of sleep a night and my life has been a nightmare.  Please someone, anyone offer me advice, information or anything.
