Clonazepam
"I am diagnosed with PTSD, panic attacks and OCD.  I have been on this drug for 2 days and I think it's great.  I am again able to drive without getting into panic attack.  It frees my mind from OCD thoughts however it does make me tired.  I take .25 mg in am and .25 mg at night.  I am hoping the tiredness will go away with time."
