When the drug companies started advertising meds for restless leg syndrome, I thought maybe that's what I had. In researching that, I found something called PLMD, that sounds more like what I have. There doesn't seem to be a reason to get it diagnosed, as I do not plan on taking medication for something that it appears meds caused to begin with. I also found aspertame and caffeine may affect PLMD. I have pretty much taken myself off aspertame, and don't use much caffeine, as I have osteoporosis.
Lately, I have a few big jerks as I go to sleep, but am not bothered in the night or toward morning as much. Last night, we went out to eat, and, as I had a headache, decided to drink some diet Coke. Caffeine helps me when I have a headache. I awoke a little after midnight jerking, and with my headache back. I am applying heat to my head, and hopefully will be able to get back to sleep.
If anyone reads this, I'd be interested in knowing if you have experience with this.
