"i have been on this medication for about 8 months now.  i started at a low dose 200mg a day and now i&#039;m on 600 mg.  300mg in the morning and at night.  i find that it makes me sleepy but what doesn&#039;t.  i am not so sleepy that i cannot function just sleepy when i know i has a good nights sleep.  anyway,  i am moody and my moods swing from very happy to super mad like many people with bipolar.  this helps we control that.  i does nothing for depression but it&#039;s not meant to.  the side effects are very mild."
