The only concern with the bupe patch is the way higher than necessary doses. But if you're only using it for one or two weeks you're not going to have any problems withdrawal-wise when you stop it. As MBC suggested, using the bupe to stabilize your life while you get shit in order and gather some comfort meds and suppliments and plan healthy meals and the like is pretty much essential to the "easy" detox these days.
cigrits, and really anyone reading this thread, please take A LOT of the advice you hear here - No, take ALL OF IT - with a dollop of salt.
Taking a benzo because you're have a legitimate panic attack, especially when used as prescribed by a reasonably able doctor, is only a failure in the books of some of the more hard core total abstinence crowd. When push comes to shove -
A failure is only a failure if you feel it is. In recovery, I'm actually tempted to say that when a person genuinely cares about bettering themselves and leading a healthier life, there are no failures, only momentary setbacks and learning experiences.
From our pms cigrits, I get the impression you have a pretty damn good understand of how dangerous and easy addiction can sneak up on us. You know what you're up against, just like you understand the risks of using benzos or buprenorphine. In fact, IMHO you've been a bit overly hesitant to use something like bupe or a benzo when you really need it, which, although certainly not a bad thing, keeping medication from yourself that will do you some genuine good is not a good thing either.
When we have a history of dependence, addiction, whatever you call it, taking a potentially addictive substance, whether it's your former DOC or something else, is always necessitates a cost-benefit analysis. If the potential costs outweigh the benefits, that's a pretty good indicator you shouldn't take it.
You will head from many people in the recovery as abstinence only community, who take this very narrow approach, that you should never take anything related to your DOC or any potentially addictive substance again, ever, at any point in your life, regardless of whether you liked it or not, PERIOD. Some take it to the extreme of saying you should never take any psych meds or prescriptions (or OTC meds) either. These people are very out of touch with the modern treatment and understanding of addiction.
Erring on the side of caution when it comes to any "addictive" medication, and avoiding illicit drugs on the whole (with the exception of cannabis and some psychedelic perhaps; the problem with using illicit stuff is that it often puts us in situations where we have ready access to our previous DOC or other much more dangerous drugs than the weed or magic mushrooms we wanted to get), is some very mature shit to be doing. Really a healthy outlook given your experience and goal to begin a meaningful recovery from addiction.
It's a really great idea, actually it's ideal, that you see your GP, have a physical and get yourself checked out for the anxiety you're experience. The anxiety and panic attacks may or may not be a part of some lingering withdrawal your experiencing. Just because you're over the acute phase for the most part if not completely over it doesn't make that any less real. It is just as if not more likely related to either an underlying disorder or simply the stress of transitioning from an addiction free life. It's kinda a shock to the system generally speaking, ya know?
I wouldn't mention anything to your doc about addiction unless you already know for yourself that they're very open and understanding, and will not write off the positibility of prescribing entire catagories of medications just because they've labeled you an addict and believe that as an addict you will get addicted to any addicting substance. Unfortunately, most addiction specialists out there are some of the worst doctor's I've ever met, and the majority fit the bill of the kind of doctor I just described you should really try to avoid. They won't be able to provide you with really rigorous care, and will be biased the whole way - even if they're probably be less biases than other doctors who still treat addicts with nothing but spite or at best paternalism.
You want a doctor who will work with you, not look down on you. You do not want a paternalistic doctor who is convinced they know better than you what you need. That's simple bullshit, through and through. And although a good working relationship with a good doctor can provide immense support, especially in the first year or two of your recovery period, it's not essential. Many, many folks - I'd actually be willing to say most - have done it successfully before you without the help of a doctor who has any idea of what was going on, if there was a doctor involved at all.
Keep up the great work cigrits! You're doing fantastic.
