I have been put on a fentanyl patch 25 mcg recently. I have a bizarre circumstance that my body adjusts and clears out medications in an expedited way. For example, over the last three weeks, I have gone thru Vicodin, then Norco, then OxyContin, now Fentanyl. I will be having surgery on 3/31, then hopefully my painful condition will start to improve. With all the posts on Fentanyl withdrawl, I am terrified of going thru that. My question: with short term use, will withdrawl symptoms be as severe as long term use, and if so, what is the best way to reduce/avoid withdrawl?
