TOD:
I think a couple times I've slept for 10 hours after pulling an all-nighter the night before.
The shortest of I've ever slept was 90 minutes, which I did TWO nights in a row, working on a project for work. It gave me a splitting headache and a sour stomach. I left work early the second afternoon to go home and sleep. My mom called wanting directions to my house, but insisted on calling me back an hour later to get the actual directions. I don't know why I didn't just tell her I needed to sleep. Well, it didn't matter because even though the phone was right by my bed I slept right through all her ringing. She thought I was mad at her and just not answering.
