Normally I try to get at least 7 hours sleep...if I miss one night's sleep I start to get manic. If I miss two nights sleep my mania starts to turn to pychosis. Nothing fun about that as I become loud and short tempered and I can't bear the sound of other people's voices.
So I try to make sure I get sleep. If only 3 or 4 hours in a 24 hour period...then I have a nap...it is esstential for bp people to get their sleep.
