Lack of sleep warning

It would be cool to have a notification letting you know if you need to take time to actually sleep. I’m a workaholic and suffer from insomnia. Like probably most ppl who purchased the app. To have a push notification warning you, not the graffics only, like a sleep deprived notification letting you know the hours behind or leading right to the graffic that shows you statistics.
