Buvidal injection

Hey, sorry if this isn’t the right sub for this. I was on suboxone 8mgs a day for about 8 months but kept misplacing my takeaways and just wanted the extra freedom of the injection so I got my first 64mg buvidal injection on the 4th of Feb. I was curious if anyone has had the one injection and just didn’t get another one? I’m on the third week, I’m starting to get a bit of pain and fatigue and the stomach issues I usually get have disappeared. Im wondering how bad the withdrawals will be if I stretch it out for as long as I can, or even just commit to coming off completely. I’m pretty desperate to say goodbye to this drug altogether but I’m also a sook when it comes to withdrawal. Any info is so super appreciated! TIA ☺️
