"after breaking my neck and back in a car accident i was given 2 40 mg oxycontin and 6 5mg oxycodone ir per day. over a period of 12 months the effectiveness decreased. introduced to opana, they worked 10x better without having the euphoric feeling (major for me). due to cost, i switched from opana er 2x40mg. per day to the generic oxymorphone 3x30mg. per day. although generic does not last as long as the opana brand, taking 3 x per day (every 8 hours) works very well. rarely do i have the level of pain i used to while taking other medicines. if i could take every 6 i do not think i would need to take as many ir pills as i do."
