Rapid cycling is classified as four or more mood episode shifts in a year. Some people cycle much more frequently than that - weekly, daily, even multiple times throughout the day. Everyone's cycles are different. Some people will be manic for a few days and others for many months. And sometimes the same person can have different lengths of episodes.

So, I'm afraid there's really no good answer to your question. All you can do is try not to get any higher and work with your doc/therapist to help you come down.
