Simplify your life by moving your microwave to your bedroom, setting it to cook on the lowest setting for 6 hours when you go to bed ;)
Don't be. Hell I can "function" with my shoes tied together.
I can "function" with some marijuana and some whiskey in my system.
I can "function" on 4 hours of sleep. It's an awful day and I'm more rude and impatient, but if I did it for years I'd be telling people I can fully function on 4 hours with no negative side effects.
Now notice that the current US President has been severely sleep deprived every day for decades.
