I am a 53 year old male. I have long suffered from mild to severe depression and have taken Zoloft for years. 3 months ago I had a liver transplant (not alcohol related) and had been taking 10mg oxycodone until 6 days ago. Also, my wife and I are separating soon. My surgery recovery along with our impending separation and apparent withdrawal from the oxycodone is taking its toll. How long should I expect the depression withdrawal to last? Any suggestions?
