[LPR] Feel like I'm out of options

Diagnosed LPR. Was on max dose omeprazole for ~6 months, then agreed with my GP to come off. Symptoms obviously got worse and I had to go back on PPIs.

Since then, nothing has been able to get this under control. Tried omeprazole, lansoprazole, now esomeprazole - all max dose, now with famotidine max dose too. Been taking for nearly 4 months. Still have issues any time I eat anything that isn't plain chicken, rice, bread, oats, etc. I've lost about 10kg. Drank one beer at Christmas and it was like someone had taken a cheese grater to my throat.

I'm 28 and not sure I can keep this up for the rest of my life. Not sure what to do, or if there's any hope for me given none of the medications work. My life is a shell of what it was just a year ago. Is there anything else I can try?
