Hi. I have frequently on the old forum recommended Magnesium for this condition. I have to take 900 plus units per day for this. I take Mag Oxide and Mag Taurate. The first is cheaper and easier to find in health stores. A neurologist recommended this for me over 20 years ago when i could not take Baclofen or the other drug I tried. It stops the jerks, which would go on all night if I did not take the Mag. If I take half the dose, the jerks continue, so it's dose sensitive. It also helps spasm, in fact, my spasms were
especially bad even more than jerks at the time it was recommended.
