I have seen many people post about the sub withdrawals. It's better not to be addicted to chasing pills.
Subutex is the same as Suboxone, just without the naltrexone. Sub might be useful for a w/d from opiates but from my experience long term is just out of the question. I had and am still having, severe w/d and PAWS from Sub and its been 2 mths since I last used Sub. But everyone seems to react different to coming off Sub. Pretty much a **** shoot in that area. Seems that when it comes to kicking narcs that there is no easy way, we pay in the end and that seems to be that.
Much luck with the Sub. If you need someone to talk to I'll be happy to try and help and share what I know.
BTW, Sub has a LONG half life so it takes a couple of days for the Sub w/d to really kick in, kinda fools ya that way.
