Hey wait a minute, I hate winter as much as the next man/woman, but murdering a snowman...really. 
Hi Setanta, I know lack of magnesium is a possible contributory factor. However, I’ve been tested and my levels are ok. Unless magnesium citrate is something else? To be honest though I will try anything if it makes it better. It drives me crazy.
For a time I was on Clonazepam, but they have bad side effects and I have heard that anti Parkinson meds work. I would rather not go on something strong though.
I’ve had every test going including sleep studies, nerve conduction, brain scan, blood tests etc.
I think it must be linked to stress.
It’s horrible isn’t it. 
Those with the benefit of the Gulf Stream may not understand about murdering a snowman, but those of us in the Eastern US are that sick of snow.
The citrate in magnesium citrate is just the other side of the magnesium salt molecule. That salt of magnesium is well absorbed, so it is one of the preferred forms. It's just an efficient way to get magnesium into your system.
All of the drugs that treat neurological conditions have side effects, and the ones that are used for RLS are a way to treat the symptoms only. There appears to be no current cure.
I empathize with you, because I also have an almost untreatable movement disorder, Essential Tremor. It's progressive, and it has gotten to the point that In the mornings my handwriting can be illegible, on a bad hand day, and it has made me more unsteady on my feet. Movement disorders are frustrating because you feel that you should always be in control of your body, at the very least. Being at the mercy of a renegade nervous system is the pits.
Back to more happy thoughts, IT'S FRIDAY, AND PAY DAY FOR ME!!!!!!!!!!!!!!
