I use to take an extremely high dose of Oxycodone...was taking for 11 years...dosage was increased over and over and over....by the time I finally insisted that my pain mgmt doctor put me in the hospital and rapid detox me, my daily dose was up to 720mg a day {all prescribed!]...that was 4 years ago! I was never a mental addict of this drug...I quit when I couldn t stand my life being robbed any longer, and except for the physical withdrawl symptoms, I have never, ever desired to take it again. My question is
Hello, The physiology usually changes back.  Furthermore, having a feeling of wanting more may be a psychological expectation AND, MOST IMPORTANTLY, it is usually NOT associated with tolerance to high doses of narcotics.  It is the usual situation that someone who expects to need a previously sky-high dose (and that is the highest I've ever heard of and I'm an addiction doctor!) will die from a fatal overdose when they go back to their previous dose. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
