"Non-Restorative Sleep Disorder - After months of agony, the rheumatologist tried Flexeril on a 10 mg, once a day (before bed) regimen. Within a week, I felt better. Within two weeks, the symptoms were gone. Symptoms included: extreme fatigue, pain & swelling in both knees, pain & swelling in one wrist to the extent that the wrist was becoming deformed in appearance."
