My neurologist just gave me some samples of Amrix, a time relased form of
Cyclobenzaprine Hydrocholoride. He prescribed it for the pain and limited range of motion caused by tight neck muscles that didn't respond to stretching excersises. This is day two and I find it a remarkable improvement. I take it once a day in the evening and it seems the main sleepiness side effect is over while I sleep while the benefits remain the next day.
