Day #3 of taking Oxycontin and I feel great, but I can't go to sleep. If I do, I can't STAY asleep.This started when I got the Rx. Do any of you have this? Will it go away? Mind you, now that I'm at home, the insomnia isn't as much of a problem for me, but I had been doing better till I started taking this. Make no mistake, I will NOT stop taking it if I never close my eyes again; it is just so nice to feel energetic and pain-free! Any advice???
