Anyone Try Belbuca?

I am switching from a pain patch to Belbuca film. It has more dosing options then the pain patch I am on and have looked at the research. I just wanted to see if anyone else has tried it. It is still buprenorphine which is a schedule III drug but hopefully ill allow me more control. The other news is my PM has decided since I am in an inoperable situation for my CSF Leak that the PM probably caused, he is willing to allow me to try Medical Marijuana and still keep me on my pain meds. At first he was saying I would have to go off the pain meds to try MM but now says that is not an issue. I have been so nauseated the last 3 weeks I have only eaten a couple times. After losing almost 20 lbs, I am willing to try other options.
