They called my pain management facility and a doctor there told them to give me 2mg Dilaudid tablets to wean off the
Fentanyl because it has a similar chemical
structure, unlike oxicodone, percs etc... I think I did something like 3 tabs a day for 5 days, then 2 tabs a day for 5 days, then 1 tab a day for 5 days. I still felt crappy, but not insane and finally was able to stop for good. After 1 month on 25mcg, you probably won't have withdrawal as severe as I did but everyone is different.
