Nova, please familiarize yourself with the forum guidelines before creating any new threads. I'm not here to give you mountains of shit, but we are a harm reduction community. We help individuals who have chose to use drugs, do so in as safe a manner as possible. We don't help people acquire drugs. We especially do not help members of the community lie, deceive or defraud the medical establishment with the hopes of acquiring drugs. I'm not saying none of us have ever stolen or done anything wrong, it's just not appropriate material for the forums. It's something that you could best discover by asking other addicts what they have done in the past in the same scenario.
At any rate, what you are attempting is a terrible idea. It's really a bad, bad plan. You could, wait the 3 more days and continue to enjoy your prescription for a drug that is becoming less and less common to be prescribed or you can let restlessness get the better of you and try to refill your prescription 72 hours early and potentially get cut off from any controlled substances permanently. When doctors put you on the blacklist, it's more common than not for them to simply tell you to fuck off without any medication to taper with. I'm not trying to call you an idiot, but really, give it some thought.
