Acetaminophen / oxycodone
"For the first year I was on 30 mg. oxycontin plus 3-4 oxy/APAP 3/325 per day.  Became addicted and was hospitalized during withdrawal from the oxycontin.  Tried to substitute the oxycodone with Neurontin (didn't work), Lyrica (didn't work) and tramadol (didn't work well enough).  Have now been on oxy/APAP for 14 years.  Your body attempts to develop a tolerance but you just need to tough it out.  Closely monitored by my doctor.  Had to sign a pledge not to doctor-shop and I keep it at 4 tabs a day, one tab at a time."
