? symptoms dyspepsia

I am a 40 year old female.  I suffer from burning sensation from the back of throat down to stomach shortly after eating.  Also excess acid when hungry.  I have been diagnosed as havine non ulcer dyspepsia after having all relevant tests.  Losec does not help.  Funny thing is I only get this in the summertime.  I do not change my diet during the summer.  I usually get this around June and it can last until September.  Does anyone else get these symptoms or can anyone help with a cure?  Many thanks.
