Is it out of the ordinary for someone with bipolar to experience some hypomanic symptoms at a particular time of day that only lasts a few hours? I get this way at night sometimes. Around 10 or 11pm, I get really bug-eyed awake and can't sit still and need to go out and do something! ANYTHING. Usually this ends up with me going shopping, at the only place open at night, Walmart. I want to go to walmart Sooooo bad tonight but I took some opiates impulsively and KNOW I should NOT be driving right now. But it sucks because I can't get myself to sleep usually not till 2-3am if not later when this happens.
