Sarina I suffered terribly from acid reflux, must have been 10yrs. I eventually took Lazsoprozac, which stopped it completely, straight away. However, the side effects were severe and frightening. I stopped the meds and tried altering my food and drink intake. To my great surprise it worked, I couldn't believe, after 10yrs of suffering I had cured myself.
No wine or tomatoes, which I loved, no pastry, no spicy foods. I swapped to: Sourdough bread from Lidle not Tesco, Lactus free milk. occasionally I will take a Rennie before bed if I've eaten too much or a little of the forbidden fruits, before this and before meds from Dr. I would take a whole big box of Rennies per week!
Changing diet is the way to go. Good luck.
