you should be able to combine them all. apap is fine and your overall opiate dose would be very minimal. I think even with the xanax, at this low of a dose, you should be fine. any prior experience with opiates and at wut dosage? Obviously its always dangerous to combine CNS depressants and im assuming the 30/300 is 30mg codeine 300mg apap/acetaminophen/paracetamol
That isn't much in the way of opioids, and if you have a tolerance to the alprazolam then you will be fine.
