How to feel fully refreshed on 4 hours sleep a night
How I did it: I hurt my back badly when I was fifteen and have since never been able to hold still in a bed for longer than four hours without excruciating pain. Since then I have adapted perfectly to this shortened sleep schedule, and feel sharper than most. I wake up at regular 4/4.5 hour intervals, and sometimes will stay in stay in bed for a few more hours changing positions periodically and having basically an extended lucid dream session. I drink alot to sleep on the nights Im too bored to deal with all the extra time I have, but even this can't keep me asleep for more than 5 hours. Its pretty weird to constantly feel like you've been awake for six years or more, but mostly its great.
Lessons & tips: Stop smoking and you will feel better. You might not sleep better but you will feel better while you are awake.
