muscle spasm
"I took Amrix last night for the first time at about 9pm. It seemed like it took the edge off the pain. I never had a feeling of euphoria like some medicines are prone to deliver. About midnight I went to bed, I woke up at noon the next day. By 1:30 pm, I was back in bed till 4pm. The medicine works great at taking the pain away, but, if you need to be productive the next day and don't have 12-14 hours to dedicate to sleeping I wouldn't take this medicine. I'm glad I had nothing to do on a Saturday but I still didn't want to waste it by spending the whole day in bed sleeping."
