I also agree you swap up the drugs to adjust for the episode. So some times you stay put, and other times, for me it seems,like there was more frequent but carefully orchestrated changes. I've been bipolar over 10 years and it appears (keeping fingers cross) that a new drug I've taken for two months, is finally helping address most of my problems. Even with it, this is in combo with two other psych meds. So, as you've read alot on this site, everyone is different. Good luck on your quest- there are a LOT of options!
