Honestly, you are probably taking a dose that is not potent enough since you're starting off. Your doctor is a little negligent, too. Just because you're competent and not experiencing active mania doesn't mean you shouldn't be hospitalized. From your responses I cannot tell that you've been deprived of sleep. You type coherently and with structure. I haven't read anything about hallucinations from you (or maybe something minor) and you seem to have a grasp of what is going on around you. It's actually pretty amazing and probably rare.

Also if you're at the hospital it would be easier for them to increase your dose in a shorter amount of time. Also, I think you need something heavy-duty. I think going up on medication at your home will be too slow. Maybe call your pdoc and ask him about an increase?

Have you tried physical activity?
