The state of being of sometimes sleeping 12 or more hours ('down' cycle), while other times sleeping 3 or less hours ('up' cycle), which are often located directly adjacent to each other. It can repeat in this manner, or be
long stretches of the down cycle and then
long stretches of the up cycle, or a
long stretch of the up cycle deviant from
one's normal routine, followed by a
short recovery in the form of the down cycle.
This word often applies to finals week and intense workweeks which have weekends to recover on. It can also apply to insomnia, where the
body exhausts itself to the point where it can't postpone sleep any more. It is sometimes anecdotally observed in conjunction with bipolar 2 and some anxiety conditions.
"Man, this finals week has me so bisleepolar."
"I feel that - I've already pulled 3 all nighters this week. Can't wait for the weekend."
"I
hate my insomnia... I feel like I'm bisleepolar. Even with the
green butterfly medicine, I can't sleep more than a couple hours each night, and then when I'm so exhausted that I can sleep, it's for a day or more."
