"I have had great difficulty sleeping (staying asleep) for years and years and the only thing that really works to help me get a good night sleep and also help with my fibromyalgia is Flexeril. I take 5 mg most nights and on occasion possibly 8 mg (breaking the 10 mg) and sleep like a baby with no painful muscle cramps in legs and come completely awake in the mornings with a cup of coffee. The wonderful thing about Flexeril is that it also relaxes the MIND which can keep a person awake for hours thinking and rethinking &quot;to-do&quot; lists as well as other anxious thoughts.  I have taken it for a long time and have no adverse side effects. "
