Icelander and Balanchine,
I really appreciate all your help with this as it's such a relief knowing I have some recourse when things get really bad. I intend on using it for "special occasions" and not on a regular basis.
When I went to bad last night after such a good night's sleep the night before, I was worried sleep wouldn't come easily, but it did. I wasn't in much discomfort on any front...my feet were ok, my back wasn't bad, no burning at all...and I drifted off to sleep on my own without having to do anything for pain.
Lest I forget my woes, though, I was woken up at 5:53 a.m. by a frog croaking out my bedroom window and my back was killing me. Never got back to sleep after. Equalizing karma.
