If you have any left, break them into small pieces and try your best to ween. If that ship has sailed, If I were you, I would contact my primary care doctor and ask for a valium taper. I would also ask for clonidine (not a controlled substance but helps withdrawal a ton!). I am not 100% on your history so the only safe thing I can advise is a doctor as benzo withdrawal is no joke.
I am currently considering switching from Suboxone to Methadone for pain issues and dreading the day before that I have to not take any Suboxone or benzo's. Also, I am in a similar boat as you and doing my best to ween and it's working. It wasn't a terrible habit but necessary for the season of my life. If you decide to do it on your own, look up some supplements, some actually help!
