I can't go without 10-15 minute power naps in the afternoon or evening. Whether it's physically effective or just placebo, it feels essential. That being said I drink coffee before the gym at around 7-8pm, which probably isn't the optimal time (though I have no problem falling asleep at 12:30-1:30am which is when I want to go to sleep).

Power naps can be very effective when used right (i.e if you're consistent with them). In the last month of my semesters I switch my sleep over to Polyphastic sleep schedule. 6 Hours of sleep at night and one 20minute nap in the afternoon. It gives me more time to study for finals/finish up class projects.

Do you mean polyphasic sleep? If you sleep two times in a 24 hour cycle, that's biphasic sleep.
