Are you me? I had the same experience but I'm at 450mg + adderrall.
It's basically a miracle. Not sure if the newer non-stimulant adhd meds work in combination with buproprion if you don't want a stimulant or can't take one or get one.
I will probably drop down the buproprion now.. I suspect that buproprion is basically just less effective Adderall.. however, the generic buproprions really have bad quality control. I think there's a big scandal there brewing like before.
