I personally wouldn't do either a methadone or suboxine program ( if I were to do it over again ) Epiphany.
I've heard nothing good about methadone programs. And I did take suboxine for 6mos after quitting heroin. I jumped from 2mg subs on Feb. 25 & the w/d's last a long time ( a lot longer than heroin w/d's. ) I mostly have good days now, but then bam! Another of w/d's ( nothing horrible, just feel like crap. )
No info on w/d ease, sorry.
Getting clean takes a lot more than just detox. You need to learn to live clean again.
