What was the latest time you ever gone to sleep?

Boo Diddly

Shine Sprite
1 AM.
 
I've stayed up for a whole night before, and then went to bed at about midnight the next day so I guess then.

Excluding that, I've stayed up at about 3ish.
 
10 am probably

although i have a habit of staying up for more than 24 hours, which is stupid.

One time i stayed up all night.

i regret it
Staying up all night, especially when you woke up fairly early in the morning the previous day, is the quickest path to emotional delirium.

That said I've stayed up to 6 before and been fine, as long as I woke up at 12 PM the previous day. It's really not how late you stay up, but rather how long you have been awake.
 
Is the Russian Sleep Experiment true?
 
Stayed up for the whole night about 10 times or so before.

But yeah I suppose the latest normal time was 5 am from some months ago.

Basically I saw it was gradually getting lighter and I was like "meh time to go sleep".
