ibromyalgia
"I have had fibromyalgia for over 15 years.  When my muscles feel extremely "tight"``I definitely hurt more.  Thank God for Flexeril!  I take 10 mg before bed and this helps me to sleep and feel less muscle pain.  I tried to live without this medicine for 1 week and my pain level went up considerably and much more muscle spasms and tightness.  I do have a dry mouth especially after I wake up.  I do work night shifts as a nurse...this helps me to get better sleep in turn making me feel better after I get up. "
