Madonna "Papa Don't Preach"

Despite her larger-than-life personality, Madonna stands at a mere 5-foot 3-inches. She also suffers from insomnia with her sleeping issues dating back to when her mom died at the age of 30. Six hours of sleep is a success according to Madonna.

The Fifth Dimension - "(Last Night) I Didn't Get to Sleep At All"

For a few years in the early-2000s, I worked an on-air shift each Saturday and Sunday morning from 5-10am.  Let's now take a peek at what I did on the Friday and Saturday evening prior to working those glorious early-bird shifts: here we see Todd staring at the clock and counting down the amount of sleep I would get if I fell asleep right at that moment.  "OK, I can get five hours of sleep if I fall asleep right now."  This process would get repeated each week and usually culminated in me accumulating about two to four hours of sleep.
