Well, I feel pretty casual .... but then again I guess if I ask about something that will allow me to abuse more often you'd be right. I only do about 60 mg a week I simply don't have to money to waste on them. I really only do about ten milligrams when my body is ready to quit and it picks me back up for the haul, then puts me to sleep when I need it. I should probably stick to recreational use I suppose. I've read some pretty uninspiring stories about the agonies of opiate WD which I have been lucky enough not to have in over a year of use. Guess I'll just keep my priorities in line.
That's good to hear mate, you still seem to be in control, didn't sound like that from your OP. Also, you haven't raised your doses, which is a good sign as well, and you only use to self medicate if needed. However, I'd advise against recreational use, this is when opiates will lure you in. You've tasted heaven, which could quickly turn to hell should you find yourself in a situation that allows you to use more, be it financial or a simple change of mind.
Keeping your priorities straight while using is hard, too hard for most people. Don't believe you're in the clear because you've avoided physical dependence for a year, the time will come when you binge for a month and suddenly the oxy has its hooks buried in your body. Every addict once believed they were casual users and they wouldn't let it escalate, only to be proven utterly wrong.
Obviously, I can't make you quit, nor would I want to, it's your choice after all, but you seem to severely underestimate the addictiveness of opiates. Try to go without for a while, you'll crave for them, if only psychologically. And you've already noticed that opiates are a cure for nearly everything, so please watch out and never use them to get over difficult times, addiction can catch you most easily when you're at your weakest.
Sorry for the preaching, I don't mean to insult or belittle you, just give some honest advice. I hope this doesn't come across wrongly, as I'm the last person who'd deny another to make his or her own choices.
