Back when I was opioid naive (such a long time ago), when I had severe pain from a tooth
abscess, 2 Percocet tablets removed 90% of the pain
4-6 hours, just like it said on the bottle.
Chronic pain doesn't work this way. Long acting OxyContin can be delivering the same 10mg of oxycodone to my bloodstream every hour, but it does not remove 90% of chronic pain -- it can't, because my nervous system never stops generating pain signals.
