My humble gratitude to John J - REI Community Manager who recommended inflatable portable GERD pillows! This is EXACTLY WHAT I'VE BEEN LOOKING FOR, but no one in medical supply that I'd contacted had ever heard of them! WHAT?
I've looked up a number of them on-line and trying to get a handle on reliability and lifespan; I am planning a three-week trip to Ireland in September if we can get through this COVAD-19 pandemic by then. Worst-case scenario much like the old famous blow-up air bed popping and deflating in the middle of the night, I can always carry a patch kit or an extra inflatable GERD pillow! Thank you! Thank you! Thank you!
