I'll second the motion to talk to an addiction specialist.
You're really rolling the dice combining two central nervous system depressants with a stimulant. Last month, I had a kid across the street OD while speedballing, and he was lucky that he pulled through. It was more than 12 hours in the ER before he was out of the woods.
For me it was frightening to see that comatose body. My legs were like rubber and I worried about that kid all night.
Wish you the best and try to cut back, please?
