About 25 years ago, I found I was in a cycle like that.

It was terrible; I would wake up with panic attacks so bad I thought I was dying. Once I aspirated stomach acid in my sleep. Gross and painful, acid burning in my lungs.

To make a long story short, I learned I had severe very sleep apnea. Once I got a CPAP, I slept much, much better, and the acid reflux vanished. Anxiety mostly went away, too. Changed my life.

I'm not saying that your problem is like mine, but if you're not getting relief, the trouble may lie elsewhere.
