muscle spasm
"I took my first dose today around 4 pm to help ease tension in my neck that caused a terrible 3 day migraine. The first two (prescribed by a doctor) made me sleep only two hours when I was supposed to be out for 6 hours. I still had the migraine of course and it didn't have any negative side effects nor did it help that first time so I took one more 5 hours later as i was getting ready for bed. It is currently putting me through hell because of nausea, an upset stomach and now I cant even fall asleep.
