I'm 52, female and had been having knee problems. Starting taking boyfriend's supply of percocets. Started off on an as-need basis. Gradually, over time, I'm using 2 tablets every 4 to 6 hours. Only just recently, when I inadvertantly ran out, did I start to feel the effects and realized that I am an addict. How do I begin to wean myself off these drugs? What are the side-effects and how long can they be expected to last? I am a professional and can't afford to be off work for any prolonged period of time. No health insurance and no safety net, so rehab facility is out of the question. Please help!
