I would be cautious of using stimulation as a way of keeping out of the black pit. If the switch from mania into depression has anything to do with manic exhaustion, further stimulation could act as a destabiliser. Maybe - maybe not. I just know that when I have been manic for a week or more, I tend to become less stable. The worst thing for me is if I really lose my cool with someone (and it is usually screaming intense), I plummet into heavy depression for a couple of hours (mixed). If I'm manic at the time, I usually bounce back out again, but if it happens while I'm switching, then I'm in really dark syrup and need protection from the suicide demons that swoop in for the kill.
