Regarding your considering using opiates to treat you GAD, first of all you would have to find a doctor that would be willing to prescribe pain medication for your anxiety disorder. This might be harder than you think as doctors are under the microscope these days, when it comes to prescribing pain medication. And opiates are not a known treatment for psychiatric disorders, not even considered "off-label", so again, any reputable doctor will not write you a script for an opiate to treat your GAD.
Also, as you seem to be aware, long term use of opiates causes one to build up a tolerance to them, requiring more and more medication to achieve the same results.
And there has been lots of stories here on Anxiety Zone, of individuals that were prescribed benzodiazepines, got hooked on them, and then their doctor suddenly pulls the plug and won't write them another script.
I'm really sorry for what you are going through, Wrstone. Lots to consider here.
The very best to you!... Chuck
