The pain lasted with me pretty much most of the night, and I finally fell asleep again around 5:15 am or so. Woke up with some more pain in the throat from the reflux around 7:15, so took some more Gaviscon. Slept again until around 8:20 am. So not a lot of good sleep last night.
I'm still coughing somewhat now, and the acid reflux residue is still there, so my throat's burning a bit. I'm hoping that eating some breakfast helps somewhat. We'll see.
