Muscle Spasm
"I have been taking Tizanidine for about 8 months, having read about it in a medical publication.
I have: Fibromyalgia caused by: A Chiari 1 malformation (no surgery), Adrenal Adenoma (excess Cortisol), Bilateral Peripheral Neuropathy, 6 damaged disks, Hiatal Hernia, Narrow Esophagus, Nervous/Acid Stomach, IBS (had), Severe Pain in upper leg muscles, tight hamstrings on legs (HAD/is effectively treated by medications), RLS, Ehlers-Danlos Syndrome, Sublaxity and Double Joints, POTS; vasoconstriction, Raynauds-like feet, see stars with hands over head, fluctuations in BP; 
   Tizanadine taken at night, .2 mg dosage, will help me fall into a relaxing sleep with storybook type dreams. It compliments my other drugs well, IMO."
