Went thru this 4 years ago as I suffer from RA. I stopped then but it didn't seem so bad. Please look into naicin as its a anti- depressant will flush your system and help with sleep and restless legs. It's helped me and also mentally raised my spirits, not saying its stopped it all together but a big help and good for you. Also helps lower cholesterol. I started back on codeine on a long plane journey was in so much pain somebody offered and it helped at the time got home and Dr. Was all to willing to give me what I wanted. That was march and I never even took the recommended dose, just had enough needed to increase dose so said f--- it evil in a pill never again.
