muscle spasm
"My first muscle relaxer was Valium which worked well but after NY got crazy about controlled substances, I went to Flexaril which did nothing.  Then to Tizanidine.  The first time I took it I thought someone had given me LSD. I was tripping.  It was wild and weird. I stopped taking it. One day I was having the worst muscle spasms and took it again.  This time I just fell asleep.  I had been on sleep meds but nothing worked like Tizanidine.   I stopped taking sleep meds and now just use Tizanidine for sleeping.  I take one and a half 4 mg tablets (6 mg a night). If I'm having a bad night and have to take it more than once I feel dizzy and nauseous the next day.  The problem is that I can't take it during the day."
