Great news! I am officially fused. Saw my surgeon today and he looked at my X-Ray, said I was doing excellently well and he never wanted to see me again. And since the only reason me and this fella ever hooked up in the first place was chronic, debilitating, agonizing pain, I am perfectly OK with him dumping me like this.
During question and answer time, and since the guy does have a medical degree, I asked, "So. Why do kids always barf in the middle of the night?" Without turning a hair, the nice neurosurgeon said, "Hormones".
Turns out, as part of the diurnal cycle, some hormone drops in the wee hours and this reduces some kind of pressure and if there is any inclination, then starts the horking. "They're not doing it just to be ornery."
Huh. Good to know.
