I agree with the others that it sounds like you both have an addiction problem. I too hope you both decide to get some help with that. It can be tough when two people have an addiction problem at the same time, as it's hard to focus on yourself and not worry about the other.
Good luck.
By the way, it can be harder to get off Xanax than Oxycontin.
oxy is the worst drug for long term pain. I dont know if you have pain. You did not say. Oxy has a 2 hour half life which means it goes out of your body really fast and you build up a tolerance really fast too. I would suggest to switch to a longer lasting med and taper off and quit. eventually oxy will do nothing for u no matter how u take. Been there done that.
good luck
Yes, it sounds as if you are both addicts. You must be buying these pills on the street. If you can afford that, you can afford to pay a doctor to get help.
Your questions are a little hard to understand....
But I will also say this.. it sounds like you both have an addiction and need help. And this forum is great for support. I hope you both decide to quit. Good luck to you!
