Wow... 1600mg! I hope it helps with controlling your mania (I'm also sorry you're experiencing that right now). I know my pdoc would never approve even the 1200mg dose, though maybe I can convince her to go a bit above 800mg eventually (though I kind of doubt it, as she's a stickler for protocol). Good luck with the temporary increase and I hope it helps to stabilize your mood!
