Wake up, first thought is "where the bleep am I?" I know it’s not home when the bed sucks and I’m either freezing or melting.
Time passes. . .
Second thought, “why did I wake up?” 1st Alarm, 2nd alarm, phone, gunshot, master warning, or nature call.
Time passes. . .
“Do I gotta get up?” The amount of time it takes to get to this point depends on the second question and I usually check the phone’s clock. I unplugged the room’s alarm clock the night before.

If it’s an “oh bleep I’m gonna be late” it takes under five minutes to get out the door.
If it was a short overnight, it takes twenty minutes.
If it was a normal or long overnight, it can take an hour.
If I’m on reserve or on a really long overnight and woke up just ‘cause, I might not get up.
