Lamictal helped the depresive side alot for me. i was bouncing back and forth every 5-7 days for almost a year with the down side being really low and the highs being mildly hypomanic.
I started slow on dosage, bin a month and still at 50mg. i was hypomanic for the better part of the first three weaks. was only sleeping 2-3 hours a night, that was the only sucky part. crashed last monday, but only felt blah not depessed. so far so good
