Another important factor if you wanna come off meds is to do it when you are in stable phase in your life. Do not mess with your regimen (if it is working) if you are at the same time going through some life changes or drama.

Do it slowly and preferably under supervision. Learn alternative coping mechanisms, because you WILL get bit more emotional and unstable. Not necessarily unbearably, but it is gonna be more intense and sometimes out of the "normal" range. But you can expand your comfort zone (check out Tom Wotton's blog Bipolar Advantage here on PC for the concept), so highs and lows will not throw you out of the loop so much as you get used to them.

It's good to have a good support system to fall at (and somebody who would friendly warn you if you are becoming bit of out of control mess).

Some people report it gets better with age (teenage hormonal craziness passes and you learn to live better).
