I only take 25 mg at night, my rn said to start taking two at night to stop racing thoughts in the moring, they are still there. I seems I am not getting the right amount. I know during PMS it is much worse. I have taken it during the day when I don't work. It does not make me tired just calms me. Today I'm PMS'g so I have decided to take half before I go to work, if I get tried I will come home. I have to try this my life is unmanageable. Any comments?
