In what situation will you most likely feel sleepy even of you had enough sleep the night before?

Waiting for an appointment. I always want just… more… sleep.

- immediately after waking up.
– sometime in the afternoon.
– after eating a large meal.

First line of Moby Dick. Call me Ishmael. zzzzzzzzzzzz………

When I talk to my friend in Australia. The 16 hour time zone differences usually has one of us start to yawn.

TL:dr – zzzzzzzz

Ditto:
– immediately after waking up. (within 2 hours)
– sometime in the afternoon.
– after eating a large meal.

Warm room, boring lecture. History of Roman Law at 8 am…

My work meetings.

Doing my taxes.

Not enough coffee the next day.

If you missed your usual caffeine hit.

After a large meal.

If you spent a lot of time in the cold and finally warm up, especially if you lie down.

If you spent hours in the heat and sun.

If I had crappy sleep for the previous 3 nights. Getting one night of sleep may not make up for it.

Another scenario might be with the definition of “enough”. I’ve had nights where I wake up frequently and sometimes am up for half an hour to an hour. My wife and I have had this discussion. When you add up all the hours I was actually asleep, I might have 6–8 hours. That would be a good nights sleep if it was all at once. But because it was so interrupted, I don’t view it as the total number of hours. I didn’t get the rest I needed.

If I have a long drive and start at like 6am I will definitely be sleepy around 8am.

Most anytime if I am not engaged in something physical. I am actually having tests and going to Drs. to figure out what is the matter with me.
