"i am diagnosed bipolar ii. i&#039;ve been taking this for 3 years now. i increased the dosage up to 400mg at one point and became very dizzy and nauseated. although, for the majority of the time, i took 150mg twice a day, but now the effectiveness is wearing down.  i give this medicine a 7 because it definitely helped stabilize my moods and i became less irritable.  i&#039;m discontinuing my use this week to try lithium.  i hear great things about lithium and am tired of the inconsistency i&#039;ve been getting with lamotrigine as of late. (also, the possibility of developing steven johnson&#039;s syndrome is totally not worth it and long-term use of lamotrigine doesn&#039;t make you immune to it of course!)"
