From your name we may be in the same age range. Especially given the total hip. My DOC also is/was Oxy and I am 4 months out from going cold turkey. I had fallen in the rat hole for three years with that shiit. Four months ago I was a newbie to this type of forum and have found it to be extremely helpful in all ways. The withdrawals are temporary but the better life afterwards can last as long as you want to stay clean. There may be some withdrawal symptom that hangs around longer than the others and may be more difficult and frustrating but will eventually go away. Mine was insomnia that was very difficult and took 3 months to resolve. If you had convinced yourself that pain was your reason for using you may worry that pain will worsen/return. Many have found that the pain actually lessened or went away altogether once the dependence was gone.
