Redhata, the medications lessen the possibility of an episode occurring but it is not a cure. Some people experience break through symptoms despite being on meds. Medications will not cure bipolar disorders but will help to treat the symptoms.
My boys are taking a combination medications and supplements to manage the bipolar disorder. This is not a perfect fix either but taking less medications allows them to have fewer side effects and a cleared head.
I don't know that I really helped you. Continue taking medication. Without the meds you run a real risk of having a severe episode.
