My mistake, I apologize... You are definitely not alone though.
It took my dad putting together a little mini-intervention, making everyone at work tell me I had a problem, before I would even consider maintenance treatment. I did do it eventually, if only to shut everyone around me up, and for a couple months I still wanted my damn oxy pretty bad, but after a short while I realized that just simply not having to live like that anymore was a tremendous weight off my shoulders, even if I was still technically dependent on opiates... Even more so now that I'm finally rid of all of that shit. Sure, I can still hear the little devil bangin' at the gate in some dark recess of my mind from time to time, and I probably always will, but I've got the keys, and all the hell I've been through trying to rid myself of opiates is worth more to me than letting him out for even a second...
I wish you luck, life is not something that should have to be endured like this. I would definitely consider maintenance if there is no serious medical need for the opiates. Or if there is, perhaps methadone might be a better choice than bupe since it's a full agonist, but it would likely still have the same mental relief from that constant chase... (I'm not very familiar with the world of methadone though.)
