The doctors are giving me a choice of switching to 150 micrograms of fentanyl in patches next month from 300 milligrams of oral time released morphine a day.And I don't know what I should do.I have been taking the morphine for 9 years,and it's not hardly helping.Of course,I have a very high opiate tolerance.I have never injected the drug.I don't even know where I could get needles at.But what I want to know is,if the patches don't work,is there any way that I could get them to,and are the fentanyl patches better than morphine pills?
