Male 22, crazy acid reflux at night

Hi everyone, I never thought I’d say this at 22, but I’ve started suffering from acid reflux. On top of that, I have an extreme anxiety disorder, so it’s really taking a toll on my mental health

But it’s extreme—every day when I lie down, I suffer. I don’t drink caffeine, sugary drinks, or carbonated drinks, and I don’t eat for about 5–6 hours before bed. Before this, I’d take omeprazole once or twice a month depending on my symptoms, but suddenly, out of nowhere, this living hell started, and I don’t know what to do anymore. I’m seeing my doctor on Thursday, and in the meantime, I’d appreciate any advice or tips you might have. I’m definitely open to natural remedies, Chinese medicine, etc.

Of course, I've been looking into it, and it could be H. pylori—though I really hope not.

I'd like to hear your opinion—what was your experience like?
