4 hours? You are insane (in a good way), mate. Any less than 7 hours and I literally can't even wake up. If I force myself, my body will literally not respond to my commands and getting up and straight becomes as hard as deadlifting 100kg...

I used to be the same way, but I went on a Zero Carb diet a few years ago because of some food allergy problems and I immediately needed about an hour less sleep.

Also I have an ADHD medication that I take first thing in the morning, and it wakes you up about 100x better than coffee, sort of short circuiting your biology and making you a morning person.
