is this a acid reflux?

i am complaining of sore throat since march 2014 followed by common cold ,cough and sneezing with a little burping,i took some tonsil medicine and it was gone . but again after two weeks i got the same symptoms plus one morning i discovered a little chest pain and then vomitted twice just cough no food no water. i went to the doctor, he prescribed me omeprazole 20 mg once daily fr 3 weeks .which i have started taking one day back but i am really scared after reading its side-effect in the leaflet as my doctor didnt discussed anything before handing me the medicine plus i am on contraceptive pills because of pcod ,so i am afraid if it will cause me any side effect lately and also i am afraid of whole acid reflux thing ,is it that chronic disease please help me if one of you have recovered after taking medicine.

I took dexilant (PPI too) for 2 months for gastritis and esophagitis and it helped with my symptoms while I was taking it. I did not have any side effect beside the rebound when I stopped but I did not stop gradually like I should have, also I don't think I was cured when I stopped. The rebound effect went away eventually.

From what I read the PPI cause problems if you take them over a long period of time: many months or even years.

I cured my gastritis and reflux with diet and natural suppements. 

The books that helped me most are "dropping acid" and "ulcer free"

thnx alot fr these information i was really scared, will also read ur books
