i guess we bipolars are very alike cuz we share the same experiences.....
when i was taking depakote, i went through the exact same thing! the best word to describe the feeling is volatile.
after my own experience with this, i have come up with a personal hypothesis that this state is caused by the meds elevating your mood.... i got able to tolerate such an extreme low, that a sight elevation can cause me to feel as if i have found happiness... but i am still in an extreme low... with increased energy and irritibility. my mind struggles to break freer from this low, and as my body and mind adjust to the medication,my mood is slowly rising, this is a form of unstable... unstable in an upward direction.
i think its the instability of mood that causes me to become so flammable.
