I'm usually not up this late, but I came back from a concert and decided to stay up for a while.

Sometimes i stay up all night, but i seem to be less able to do so without ill effect than i previously could.

Mostly until 3 AM if I'm pushing it.

I try to not be up this late, but... nights like this it happens. Especially over the summer. Right now my sleep schedule is so messed up I think I've gotten sick from it.

8am usually.

I keep trying to go to bed, but then I just want to click one more link. Then another. And when I finally stop, I can't fall asleep. I think its gotten to the point where my internal biological clock doesn't even function on a 24-hour scale anymore.

I'm up until anywhere from 2am to 4am usually :S

despite living in the UK, years of Internet and living by American timezones (particularly California) meant that for years I wasn't going to be before 8am or so in the morning. Nowadays things are a little more sensible, mainly because of work, and I get to bed about 1am - 2am. But I'd be pulling all nighters still if I could. I love night time.

2am - 4am

I am terrible, haha

12 PM - 2AM. I really should go to bed way earlier.

6am - 8am Eastern. I should probably stop considering I'm going to bed just when it started to get warm outside. The heat is compounded by not having an air conditioned house.

I NEVER SLEEP AUGH. D=

(Actually I just stay up really late due to an anxiety of sleeping XD )

10:30-11:30pm, mostly because of having to work in the morning, but also because I'm an old woman, apparently.

I am generally awake until 2-3 AM. Sometimes four. Tonight, I was up all night, RPing with my boyfriend, his sister and her husband.

Depends, I'm on this site most of the time (Yay for having no life!) so I usually call it quits around 2am but sometimes I can be on here until 4 maybe 5 a.m. 83

I sometimes go to bed around 12am-2am but if I have school it's WAY earlier.

Due to various good and bad influences, most notably my partner introducing me to late-night runs of Mythbusters on TV, I end up staying awake until 5am GMT on most nights. Really gotta get back to a normal routine :S

Go to bed at 8PM-9PM and wake up at 2 or 3AM :U

Because I get up at 6am for work I have something of a nightly ritual wherein I'll promise myself to go to bed at 10pm only to end up staying up as late as eleven or twelve, depending on what I may be doing at the time. It's still better than it was, when I used to routinely stay up as late as 1am

I usually tell myself that I'd be in bed around 1:30 but that ends up being more like 2:30-3:00

I sleep til about 11 so it works out. But not this morning because my cat decided to jump on me three times and purr very loudly.

I'm usually only up till 2:00 A.M. and if I'm up later it's not spent on FA. :P

12-1 am Central.

i go to bed around 4 in the morning and wake up around 5-8 at night depending.i think im on central time...

Surely depends. Right now I'm hitting the hay 'round 2 AM but a couple of weeks ago it was 9 AM and before that 2 PM.

and hopefully I'll adjust towards a 9 PM soon.

A seemingly schedule like unscheduled bedtime cycle!

I don't stay up late.

I stay up early.

Get it.

Yeah.

until forever....
so it seems lol, I just kinda pass out when most people are waking up lol
