ibromyalgia
"I&#039;ve had Fibro for 15 years,  I tried guaifenesin years ago, but not regularly.  I was on Lyrica And Cymbalta, but the side effects are awful.  I started guaifenesin (mucinex) again less than a month ago.  So far, I feel great.  I still have pain, but I can move now.  The pain isn&#039;t debilitating like it was.  It even help my mood, which has been a huge struggle for me lately.  Im taking 400mg twice daily for now.  I can only have hope.   Right????"
