Honestly, I only figured it out by chance. I’d never had acid reflux or anything, but during a particularly bad flare, I suddenly developed it. I tried elevating my head/torso and sleeping on a certain side as a lot of the acid reflux guides suggested and….BOOM. It was legitimately insane how quickly the tremors stopped once I got my body position just right — within 5 minutes or so (you may have to play around with the right position - you basically don’t want acid to be able to flow upwards at all). I started taking meds for acid reflux after that bc it seemed like a clear sign that acid was the culprit, and I’m almost back to normal (I don’t even need to sleep that way anymore). Not saying this is what everyone else has, but if even one person has what I do, I want to help - the last five months were BRUTAL.
