yep, opiates are the worst.
here in my town we have a bunch of heroin floating around that is fillers cut with pure fentanyl. We have people dying left and right. I have lost 3 people close to me just this year to it.
Opiates fucking suck.
The upside is when you get clear and free of them you get a really nice positive push once your own endogenous opioids start working again. You will have forgotten what thats like (I did after a few years on oxy/heroin). It is incredibly nice feeling to have those natural chemicals in your brain return and do their good work making you feel nice and warm in a healthy way.
