@pnillyg see I already know your goals in life, so Im gonna give you the straight dope here, pun absolutely intended.
Im an addict too man. I have made decisions in the past that sacrificed my stability and ultimately put me on a path to harsh consequences.
Every decision has a ripple in your life. You have no idea at the time, that taking Oxycodone just once would lead to a complete relapse, either sooner or later.
Dont fall for the mentality of "just this time". We are addicts. "Just this time" is minimizing it. If youre stable and life is decent, I would not look for trouble.
If I were you, id stop using the Oxycodone, take your Buprenorphine and move on from it.
You are on a relatively low dose of Bupreborphine and a single day of moderate Oxycodone usage should not be enough to cause a precipitated withdrawal syndrome.
You're one arm in and one arm out right now. The bullshit comes when you go all the way in, then all the way out, say, using Oxycodone for 3-4 days straight without any Buprenorphine.
I cant make guarantees but I highly believe you will be totally fine restarting the Buprenorphine.
Good work my man. Ol' Man Keif, senile and no longer fuckable, is pleased
