I've been taking Oxycodone for about 5 years now and everytime I get a new doctor I have a problem with the new doctor, they can't seem to keep a doctor, in the 5 years I've had 5 doctors I'm on my 5th one now and I am having a problem getting a refill from him. I have lung cancer and the pain med is the only way I keep going. On my last appointment he said the Oxcodone didn't show up in my urine, well hell fire I have no salava glandes from them being burned out from radiation and I drink probably 2 1'/2 gallons of water a day, seems the water flushes my system out. Stupid VA Doctors where do they come from. SGT D
