I've Had Reconstructive Back Surgery, 8 Total. I've Been On

I've had reconstructive back surgery, 8 total. I've been on Oxycodone for a couple years now and I'm hooked on them, I want off them but I need something for pain. I'm a retired garbage man of 28 years. My life suck because these pill control me, if I run out I'm in big trouble. Can you suggest something else I can take for pain I want off these things!!
