My then psychiatrist trialed me on it several years ago. I got up to 75mgs and then had a fairly horrific extra-pyramidal/psychotic/manic reaction to it.
No rash. Just lost my everliving mind (and control of my body). Very unpleasant.
Currantly on Latuda 80mg and it's OK, though do need to keep Benadryl and Benztropine on hand.
Am on Topomax as a mood stabilizer and migraine preventative. Still not quite right, but not ready to mess with-medications at this point.
Too many bad reactions to medications, and putting on 60lbs and becoming diabetic on Zyprexa, and the Seroquel horrorshow sorta soured me on messing with medications.
