I don't want to preach to you but I too have 2 pretty badly herniated spinal discs.
I enjoyed the opiates and ended up consuming more and more of them, chasing the dose to chase the high... and now 5 months later I'm in awful, awful pain (hand on heart I cried in bed tonight because of it) and it's my own fault because I didn't follow the anaesthetist's pain management plan.
They wont increase my opiates, and in fact have just decreased them due to hyperanalgesia. I'm left with Dosulepin that makes me drowsy, Naproxen that's not worth taking as it upsets my stomach, and a bit of Methocarbamol...
Just please take this as a warning that I was in your shoes, and like you, I played the system to get a quick high. And now the joke's on me because I didn't follow the pain management advice.
I know you'll most probably scroll past this and ignore it but just think about your pain in the long term. Sure it's fun to start with, but the more you take, the less options you have, and the more pain you'll be in for the long run. We're not talking about a fractured arm that'll repair in a month or two. We're talking herniated spinal discs. The possibility of life-long pain. And you're going to need to manage that pain long-term...
I know what Blue Lighter's are like with taking advice on board, or not, as is the situation in most cases. So just watch what you take, monitor yourself, and the moment you start to get cravings or lose that will power or self control. Address it. And address it properly. There's a difference between mental addiction and physical dependence. The addiction comes first, so beware of the signs before the symptoms of physical dependence kick in.
Best of luck with you spine and sciatica, it's a bitch. *hugs*
