I am SO frustrated....

I have been coughing nonstop for months now, and my doctor has been completely useless....
I believe I have LPR from all the posts I have read here....
symptoms:
constant phlemy cough, ESPECIALLY after eating or drinking
no noticeable heartburn, sometimes in the monring i have gurgling sounds.
chest xray showed nothing
cough so hard I throw up sometimes

I have been put on medicines for allergies, PND, cough syrup, EVRYTHING...

I am now taking Singulair, 2 nexium in the morning, and sometimes atrovent nasal spray for allergies...

I am at my wits end..i cant STOP coughing, its driving me nuts, and everyone around me...

my doctor says i have acid reflux, take a nexium and some singulair....thanks doc.

anyone have any suggestioons???
