My old pdoc had me on 30mg for several years, but my new pdoc was amazed that I was on such a high dose; I saw him yesterday & he raised my dose from 5mg to 10mg because I've been feeling very mixed. My new pdoc's philosophy is that you raise the level of an AP when feeling mixed, or manic, but lower it, or even eliminate it when you don't need it (I take Abilify as an AP). On these lower doses I feel like I "feel more." If I start feeling out of sorts, he simply raises the dose a bit. The pdoc said the first time I saw him I looked pretty out of it..."nobody home" kind of thing. Not to scare you (& I'm certainly no pdoc), but I developed a bit of shaking & twitching in my pinkie & ring fingers on my left hand while on the high doses...these symptoms are pretty much permanent, but have lessened since going on a lower dose. My pdoc trusts my instincts & adheres to the philosophy that sometimes less is more as far as meds go. YMMV...
