hi bigricky
gosh this is so hard to answer as different meds affect so many people so many different ways. it could be both meds together are keeping you as stable as you are and dropping one could increase the cycles.the only way to find out is to drop one, flip a coin, unless it is listed in the side effects of one and not the other, and see how you do. there are so many bp meds out there you could also try others until you find something that works without the headaches. welcome to psych central. you will find we have several forums where you can post about your concerns and receive feedback from other members. you will get a lot of support here. again, welcome
