I hope your not a rapid cycler. That means you would be having 4 or more distinct episodes that last 1-2 weeks either up or down at a time or mixed . When first diagnosed or med changes occure people have moods all over the place so "rapid cycling tends to get mentioned" But once a person find stability I feel that is when keeping score is more accurate.
Are you taking a mood stabilizer? Lithium , Lamictal? I would give a mood stabilizer a good try before hopping on an AP to control the swings.
Good luck and welcome to PC
