I was extremely dizzy (broke my toe by bashing it on the bedpost when I was trying to get back into bed before falling down) & extremely tired (fell asleep while driving--hearing the noise of my tires on the gravel on the shoulder woke me up as I was driving off the road). I only made it four days on Geodon & said these side effects are too dangerous. On Abilify & Lamictal now for mood. They are working well, though I have gained weight (Abilify literature says gaining weight is rare, but I have several friends in a support group that also gained weight on it).
