I get spasticity relief from taking magnesium in a large dose, as recommended by a neurologist. Without it I would never sleep. I take 1000 mg a day divided into two doses, one a lunch and one at dinner. I can take them any time, don't bother my stomach because I get good brands at the health store. The cheap prescription a doctor gave me here (not the original doctor) gave me indigestion. When I have been in the hospital without magnesium I have been awake and spastic and jerky all night. Might help you. Doc gave this to me when I could not take Baclofen or Zanaflex.
