"i have suffered from back problems for almost 20 years and more recently, neck problems, osteoarthritis and fibromyalgia.  in that time, i have taken about every pain medication known to man, just to have them either work slightly or not work at all.  nucynta is my god send. i am on 50 mg three times per day, although i try to keep it to one per day when my pain is at its worst so as not to form an addiction.  the side effects aren&#039;t bad to me, comparatively speaking.  i do get tired shortly after taking it, but then my pain disappears and i have energy to do things that need to be done.  i have some itching as well, but i can handle some itching and drowsiness if it means i have some pain-free time every day!  so grateful."
