My Psychiatrist diagnosed Bipolar coming from BPD.  So was already on 200mg per day.   He wanted me to increase the dose for it to have any impact on mood.  200mg is nothing for a Bipolar illness.  Took a 300mg 9pm and woke up at 5 pm the next day!!   Seeing as I work I doubt this will be the drug for me especially as I am going up to 600mg."
