"one day i was absolutely hysterically crying over a tragedy and i could not stop. i took 10mg diazepam, and when it kicked in, i became emotionless. not a zombie, but not out of control emotionally. good relaxing agent which brings a little elation. i haven&#039;t found it effective for stressing out. con: long half-life. effects of valium can be felt for a long time. pro: also stopped my girlfriend&#039;s seizures."
