Smokey update: he continues to improve. Occasional slight nausea, cured by small peanut butter sandwich. Pain level on slow decline. The searing leg pain, from which he has suffered increasingly over the past few years, is totally GONE! That was the main goal of the surgery; there was a pinched nerve in his lower spine that was causing it. Surgeon put a 10mm spacer between the two vertebrae that were touching and screwed it in place.
