The Oxy they gave me did nothing for the pain so I saved them up and used them for fun on the weekends. I'd take 3 in the afternoon and space out for the rest of the day.
I definitely don't think they should be giving Oxy to anyone. I was obsessing over them for months after I stopped taking them. I didn't ask for a refill for fear of getting addicted and my doctor told me most people have a lot more pain than I did. I suspect they were just looking for another refill
One warning, don't take a sleeping pill after stopping Oxy. I didn't sleep while taking it but didn't care. I didn't sleep after stopping and it was terrible. Taking a sleeping pill made it much much worse.
