Interesting. I naturally gravitated towards both of those methods!
When I feel lots of anxiety that can't go away, I'll take a nap - there's a good chance it'll reset my "anxiety counter", letting me deal with whatever issue that was stressing me out. When I'm low on mood / even more anxious, I'll stay awake for one night - the extreme tiredness attenuates the anxiety, and at the end of the next day, I get a good sleep and wake up in a better mood.
Can confirm. My morning anxiety (I got nervous when I had to leave the house) has gotten better since I started sleeping only 4-5 hours per night and stopped drinking coffee in the morning.
