I have had bipolar II for about 20 years. I have been on medications and did the therapy. I also was admitted to a hospital for trying to kill myself. Over those 20 years, I have had times that I was feeling fine and good so I would go off my medicines. However, I always find myself having to return back to the meds. Usually when I have my crashing point it happens so fast so I don't have time to get help before my life is flipped upside down. So to answer your question, no there is not a cure but it is easily controlled if you are willing.
