Suggest Treatment For Acid Reflux

I have gastric reflux. I ve had both abdominal scans, and endoscopy. Noting shows up as physically wrong, but the hospital told me I was the worse case of acid refluc they d ever seen. Not only does it take up to 90% of my time, but also, , even taking the prescribed medicine, omeprazole, and following a very limited diet of just herbal teas and porridge, I m still very ill, with vomiting and bouts of very extreme burping, a lot of the time. My stomach, throat and esphogus are constantly inflamed.My question is: can I get better? Ive had this from when it started suddenly, 8 months ago, and just don t know how to get better: nothing has helped. Given a choice between having to live my life like this, and not being alive, I d choose the former, if I can t get better.
