The "Jerk" is a regular bed fellow for me.

Like Mariel said, stretching and exercise is really improtant and that helps a lot; especially doing some stretching of the legs before bed.

More than 500mg of oral magnesium bothers my GI, but I take tepid/slightly warm Epsom salt baths (4 cups/bath), before bed in addition to 500 mg of magnesium when I've had a lot of spacticity during the day; which usually means I'm in for a tough night. The bath allows for some additional absorption of magnesium through the skin and that does seem to help with the spasticity and the jerks.

I also take 20-40 mg of Baclofen before bed and sometimes another 20 mg during the night when the jerks or spasms are severe.

making sure that you are well hydrated also has a positive effect.

With love, Erika
