Do you see a pdoc? Mood stabilizers do reduce the manic phase of Bipolar. Some degree of hypmania can be productive, but I know from my own personal experience with it can be a problem and even snowball, so I firmly believe in prevention, and have complied with mood stabilizer use prescribed by my pdoc, after trying different ones, I have been on one and actually I'm in the process of dosage reduction (yay!) so you may want to see a pdoc to help get things in order of some sort.
Take care,
