That is not normal by any means. I've tried Strattera, Clonidine, Adderall IR, Adderall XR, and
dexidrine for my ADHD
not a single one made me a zombie. Though, out of all of them, Strattera had the scariest side effects - and it isn't even an amphetamine like Adderall or Dexidrine. They wanted to make a med for ADHD that wasn't on Schedule II like Ritalin, Adderall, Dexidrine, Vyvanse, etc, etc.... and the outcome was actually more dangerous than those Schedule II stimulants!
