AWESOMENESS is what you can expect. I thought footballs were OC 80s but i assume u mean xanax.. also if havent done this before or at least one of the above i would hold off mixing the opiate and benzo... if u have experience then WOOT cause i love the above combo!
So ahve fun and always be safe.
Also i would do the opiate first and take the benzo as your feeling the Vics... Or else i feel the highs get lost.
Its a super duper great combo. And Vicodin are not strong opiates so your risk of CNS depression is pretty low, just dont take more than 2 vics. You will have a very nice floaty high.
