Longest sleep without breaks was about 13 hours. With a break on a single day I guess a little over 15 hours.
Over 17 hours, i guess the rhum helped.
But i enjoy sleeping a lot , like 13-14 hours on weekends.
20h is the longest Ive slept and that was after I skipped a night sleeping, I felt all groggy when I woke up 
I used to have such a pattern some years ago, but now I try to not have such habits 
I’ve once woke up around 16:30 in the weekend, which was about 14 hours of sleep or so.
Only about 14 hours. May change after winter break starts though.
How do you sleep past 12 hours?!?!?!? I can’t go to sleep after sleeping for more then 10
Being really tired.
And sick. 
Only 12 hours for me.
Aww, all you cute little normally-sleeping people… :3
Sorry, that slipped out.
To be honest, I would be annoyed if I just slept 20 hours. So much time wasted Oo
Wow lots of heavy sleepers over here. And I thought I had sleeping problems for sleeping way too much, around 13 hours tops!
Am I the only one who wakes up a little sad because you didnt had the opportunity to enjoy those ~13 hours awake? Adding the fact that soon after you wake up it will be time (you would say) to “go back to bed”?
There has been a time or two where I was sick, depressed, sleep deprived for dayz, and over worked around Christmas time…that I slept over 20 hours straight!
But I did have some crazy vivid dreams and a couple long lucid ones, so it wasn’t all a waste.

about 30h…Badly ill. Backed from work and sleeped like dead.Temp was about 40C It was about 2y ago. After this i needed about month to recover. And havent ill more after this accident. Sometimes just common cold.
Maybe 15 hours or so. 
Actually I’m not a huge fan of sleeping for that long in the mornings, because for some reason this always gives me a mild headache.
It always goes away almost instantly if I get up, get dressed and have a cup of coffee, though.
13 hours last night, the longest in a good long while >.>
On the downside, it is 3:30 am and I’m not sleepy at all v.v
Umm, that’s a coma! 
This weekend I slept from 4:30AM to 2:00PM, which is the longest I can remember. Apparently, though I don’t really know how this happened, I managed to play about 12.5h of Skyward Sword that day 0_o (and that’s why I need to get back into fitness XD).
But yeah, about 9.5h I guess? Not nearly as long as some people here. I think I might have slept for 10 hours in the summer, but I woke up in between sleeping (this was just straight through).
Really 8-9 hours is my MAX
Just slept 19 hours again.
20h+ once, went to bed at around 7:30, expecting to wake up 20 minutes after, woke up the next day a few hours before, thought I went back in time to be honest.
For about 6 weeks now I’ve been waking up past 4pm , that’s holidays for ya.
