7oh to subs, possibly sr17018?

I was on 7ho and switched to subs using quickmd and tapered down to 4mg/day. I have an appointment with a psychiatrist at the local rehab place in a few days because I was trying to get the suboxone prescription locally but am having second thoughts because quickmd seems more reliable. Since I can’t seem to taper any more though, I was considering switching to sr17018. My goal is to be off of everything as soon as possible. Has anyone been in a similar situation? I’m considering canceling the local appointment and just getting sr17018 to help taper suboxone but also don’t fully know how. I also have enough suboxone to last but keep making quickmd appointments just so they don’t cut off my prescription in case I need it. Not really sure what the best course of action would be here. Does anyone know the best way to quit would be or anything? Thanks.
