I take xanax at night every once in a while to help me get to sleep, between 9:30pm and 11:30pm last night I took 2MG of xanax. This morning, at 8:30am, I snorted 40mg of oxycodone, forgetting I had taken the xanax the night before, and now I'm worried that the xanax might dangerously conflict with the opiate. Could I possibly be at risk for overdose or should the xanax no longer have an effect mixed with the oxycodone? Its now been over 3 hours since I've taken the oxycodone and I don't feel too high, just really tired and now kind of panicky. Just to clarify, i have a decent opiate tolerance and 40mg isn't a huge dose for me, but i don't have too much of a xanax tolerance.
