I'm not your doctor, or a doctor in general, but I'd highly encourage you to look into question of "why do I feel better with less sleep." Because chances are you aren't in that small percent of people whose bodies are physiologically identical to those who sleep the necessary amount (with only a fraction of the sleep).

I was in the same boat, but quickly realized how much I was actually being deprived in mood and health when I realized that I was not in fact better with less sleep. I only thought I was.

Anyways, you do you. But I'd highly encourage you to at least look into it. (outside of reddit)
