... used to take 6, 10mg Percocets a day. I dont feel that the oxycontin is working as well as the Percocet were at the moment but I did just get them today. Could someone explain to me in detail exactly how the Oxycontin works, mainly the time released part. I think if it administers a dose every hour it should be 1.6 mg an hour and how long does each dose last? Do they eventually overlap or what? Would just like some answers and is there a way to make them work a little better pain relief wise without snorting or crushing or injecting?
