Sounds like someone just got access to some clonidine. You could have kept both thoughts in one thread, as I see you made another post regarding its effects on anxiety.
Why would you want to mix weed and these random pills? Are you thinking about trazodone therapy? There's nothing recreational, "fun", about eating these pills you just listed. Mirtazapine (Remeron) will only make you sleepy; same thing applies with quietipine (Seroquel).
Don't mix it with any. If you get some paranoia from weed then eat some clonidines, I suppose.
