@Roberta,
I think I figured out why I've been having so much trouble falling asleep.
Restless leg syndrome. I'm lying there, drifting off, and then whammo, one of my legs tenses up and has a mini spasm. I'll add it my list of things to discuss with the internist.
I read up about it on google. Didn't find anything especially helpful that I would do without first having a legitimate diagnosis.
How do I come up with this stuff. I'm kinda impressed.
