Well, IDK about the Fentanyl, but i have had w/d's from Hydrocodone and it is also pure hell, as you know! But, i would think that the w/d will probobly last as long as the hydro w/d. You know........forever! lol But seriously, probobly really hard for about 8-10 days, then just weak and sucky for the next 2-3 weeks. That's what i think!!!
Thanks for sharing...
I detoxed off the fentanyl patch over 2 months ago and it was pure hell! The worst experience of my life. I was on 150mcg and did it pretty much cold turkey. I you need any help or questions just private message me. I went through a lot!
