Yes, methadone has it's risks; it can also be very effective and return some to a quality of life they haven't achieved with other pain meds.

Rather than putting the cart before the horse and judging books by their covers, it might be prudent to see if plan B (or C or whatever) is even necessary. I think it's prudent to research any/all meds proposed/prescribed, and discussing them thoroughly with your doctor(s). However, rather than pre-judging/selecting your own medication(s), I'm of the opinion that medication selection should be made by, or with the guidance of, a physician. That's (part of) what you're paying them for.
