Self reply to add an addendum ... I almost forgot the follow up. I've also experienced weird GI pain with no cause and reflux without any indication of reflux (throat looks fine, swallowing is fine, etc.). For the GI pain, my GP prescribed a relatively low dose (20mg) of Amitrypyline, which is an old anti-depressant. Later, the GI specialist I saw recommended I double this to 40mg. Apparently it's good in treating idiopathic pain like mine, and I it may have helped me. It's really hard to say because a lot of my pain issues have occurred on and off over long periods of time. So maybe the improvement is just a natural resolution of some underlying issue, or maybe it's the medication. The theoretical mechanism of the drug is that when taken before bed it helps you sleep more deeply, and during good quality sleep your body is better able to repair itself. Absent any reason not to, I'll just keep taking it.
