Muscle Spasm
"I have severe neck pain and muscle knots in my neck.  I&#039;ve been told by my doctor these knots are essentially small bone spurs that protrude into the muscle tissue which causes spasms.  This is particularly bad when its damp or rainy.  I was prescribed 10 mg of Flexeril.  Overall, I&#039;d say it works great with very few side effects.  The only issue is some days 10mg doesn&#039;t seem to help very much.  I have taken up to 15 mg (one-and-a-half) when the pain or knots are really bad.  At the 10 mg dose I do NOT have any problems with being sleepy and take it during the work day all the time with no sleepiness.  If I take it with a pain medicine it will make me drowsy. The sleepiness side effect seems to vary person to person."
