I've always been told the "stay up all night if you can't sleep and then the next night you'll sleep great" but if you're bipolar (or maybe just me) that's a load of hooey, I've been up for I don't even know how many days, I've lost track and staying up all night doesn't make it any easier to fall asleep the next night, it's always the same. Racing thoughts all night long. Exhausted but not "tired".
