Fentanyl can be really difficult to detox from, especially CT. The withdrawals can be more intense and last a lot longer than other opiates. It's best to taper slowly if you can. Do you have a doctor that prescribes them that can help you?
It's generally administered by a doctor for Cancer patients who are past pills and need stronger medicine. They are morphine patches.
I believe it is Fentanyl Patches
i'm sorry you are feeling so bad. Days 3-4 were the worst for me, but I felt alot better by day 6. What pill are you detoxing from?
