i take avinza and it works really well for me, and even better as some oe else mentioned i am not having to much trouble reducing my dosage. i am still able to get out of be, drive, do things, make food and eat. it hurts at the end of the day but by then it is time for my nught time dose.
sorry i dont know anything about the other me
p.s. just check to make sure your ins will cover the avinza it is 300 or more a month
