Hi Ruby
I have RSD which Is a nerve disorder and no cure. I have it In my whole body. I also used to weigh what you are now and I was taken 2 80mg every 12 hours and still had pain but nothing like before the Oxicotin..The DR I went to saved my life..I also take Oxycodone 15mg 2 every 4 hours which are fast acting pills. So with both I did pretty good. I hope this helps you. I just had a SCS put In and as of right and the past 2 weeks nooooooooooooooo pain I can not believe It..And Its wonderfull. Having the pain for 17 years..Like WOW Take care Judy G
