If this medication is not working as well as the
hydrocodone, then there is no reason for you to continue it. Also,
fentanyl is a very strong medication that has worse withdrawals than hydrocodone.
I would suggest you go back to the hydrocodone. You sound like you were taking it correctly for pain and it was working for you. It should be "if it's not broke, why fix it" , not, "if it's not broke your not looking hard enough". Know what I mean?
