Natural remedies for GERD - anyone have success?

I have GERD. Specifically laryngopharyngeal reflux (LPR). I’ve had it for a very long time, and it’s the primary culprit of my insomnia issues. My poor sleep habits are - I believe - the only issue standing in my way of achieving my fitness goals.

My reflux is the silent kind. I might not even know I’ve had it if it weren’t for poor sleep quality. I do clear my throat a lot. I can clear a good chunk of phlegm out of there at any time of the day. I have excessive thirst at night that isn’t quenched unless I chug huge gulps. I don’t believe I’m actually thirsty or dehydrated but aggravated by the reflux.

My doctor prescribed Prilosec about a year ago, but I don’t like taking medicine. After some bad bouts of insomnia the past week, I decided to take it. This is only my 2nd day taking it, and my stomach cramps are almost unbearable. I’ve read this is a common side effect.

I just want to fricking sleep.

I’ve lost a lot of the extra weight I’ve been carrying around. Not much. About 15 pounds. I could shed maybe 5 more to hit more of an ideal weight. 10 would put me square in the middle of that BMI zone. So I’m not sure it’s the weight. I rarely drink alcohol. I’ve been cutting out refined sugars and have limited my refined carbs.

I read that a Mediterranean diet has as much success tearing LPR as proton pump inhibitors do, but I’m over spending my nights awake googling about acid reflux.

Any suggestions?
