if you get the tiny germ of an idea about using, the idea is quickly beaten down by realizing that even if you did
use, it would have no effect.
In that way, the craving reduction is really a ‘psychological’ thing, not a ‘chemical’ thing—as is the case with buprenorphine.
If you are maintaining sobriety, I would be very reluctant to go on buprenorphine—unless the cravings were really bothering you so much that you couldn’t stand it.
