It is a new drug to your body.
Mixing benzos
and opiates can be deadly. Thats what half (or more ) of these celebrities have been dropping dead from over the years (and of course many, many more normal people too ). Anna Nicole SMith, Heath Ledger, Michael Jackson (although it's not official yet), etc. And are you taking 2-3 lortabs at one dose? or spread out thru the day? if you are taking them all at once, you definitely should not be taking the xanax with it.
