Medication assisted treatment

Lots of talk of using bupe here. I tried and had no success. Of course I did it all wrong but I tried. Anyways, does anyone have any experience with a full agonist MAT? I’ve got an opportunity to go to a clinic every morning for an opioid medication that they dial in to my needs. (I was warned by a bot that I’m not supposed to type drug names). I’m supposed to start treatment tomorrow (Monday). I’m worried that the urge to use 7 on top of this medication will be strong and I have extremely low will power. If this doesn’t work, I’m going to rehab. I don’t want to do that because of work and family but I MUST get off of this shit. Anybody been down this road?
