You can spend the day running around in a circle screaming or bang your head into a wall every 2-3 minutes. This has been clinically proven to keep people awake but may result in confinement in a mental institution.
Think to yourself: If I don’t keep it together, I will be useless to my husband/wife/kids/parents/employer/employees/friends-in-need, etc, & that’s the whole reason why I was zoche to say modeh ani in the first place. HKB”H gave me another day, ,even in this condition, & I’m going to put one foot in front of the next, no matter how little I accomplish, because the alternative is not an option. And tonight I’ll put myself to sleep earlier, like I should have last night.
