Well being on suboxone, I know it's a strong opiate but if your on maintaince with u will disagree. But subs, phenibut, gabapentin Xanax and weed. I use to do this without phenibut(and still do sometimes) but the phenibut really adds something to it that really makes it feel like a full on agonist.. Euphoria, nodding, stuff that you never get on suboxone. It would be stupid to do this combo unless you have a tolerance to bupe and start low with all the garbage tic drugs
