I say ... it's a lot smarter to quit opioids without the aid of other intoxicating substances.
But then I would also say ... there is something to be said for the notion 'do what you gotta do' to get through the withdrawals
But I say that with a major caveat ... that should be 'provided that what you use to do so isn't going to endanger your life, or give you other withdrawals to contend with'
What I mean is ... it would be highly inadvisable for anyone to use a drug they've previously had problems with in order to ease the pain of opioid w/d's. And using any intoxicating drug such as benzos or alcohol, regardless of whether you've had a problem with them in the past, lessens your chances of a successful recovery after your withdrawals are over. So you're better off without them, in general. But if you DO use them for w/d purposes, you better make damn sure you stop them as soon as you start feeling better. Otherwise, it's real easy to have a whole other problem to contend with...
