I don’t even know what Norco and Xanax are…. but I’m sure you could find something to replace them with that looks similar. The placebo effect might soften the blow for long enough for the cold turkey thing to work.

Random note: the only reason cold turkey wouldn’t work is if she is particularly weak-willed. She needs to strengthen her resolve.

There are programs available that are free. You did not mention the state you live. I had a family member who was addicted to prescription drugs and the detox (2 week stay) was free. She was receiving little income before her treatment,,so I’m not sure if low-income was a factor.
