Very good results from Clonazepam for me, and for many others it seems. Pretty mile compared to the Lithium classed drugs, and it has a long life, so it stays in your blood pretty evenly. Just make sure you always take it twice a day and not just when you feel like your having an episode. If not it wont work to its full potential, and you will end up spiking. And turn your day into a rollercoaster.

Good Luck with it though!
