Generally, I sleep no later than 11. I'm usually out by 10, 10:30 though. I'm usually up pretty early, like 7:30. I'm not much of a night owl, never have been really. Plus for my day job, I do need to get in during the mornings (like 9 or so), so I need to have my sleep, otherwise I just can't function. 

I'm told that I'm actually an anomaly for people my age, since I sleep early and get up early. *shrug*

I sleep just fine. It all boils down to what you eat and an imbalance of nutrients. This affects behavior, sleep, mood, causes anxiety, etc. My suggestion - get a crockpot and throw in a whole bunch of vegetables, chicken, etc and eat. You'll feel better everyday!

As a artist I "volunteer" a lot of extra hours, so I have a very irregular sleeping hours.

 

After a job where I had to do multiple days of 24 hour work shifts, with 6 hours of sleep in between each, I had swelling and stomach pains.

Some of my organs where beginning to pack up. It turns out that lots of coffee, only fast food and little sleep is bad for your heart and kidneys.

 

So now it doesn't matter what time I wake, I always force my self to go to sleep in 16 hours.

Food is king. The kind of food you put into your body seems to determine your overall mood and even things like motivation from what I have found. Eat well - stay motivated, young, and happy. Get a slow cooker - easy way to cook and healthy!

Currently I go to bed around 3 AM and get up around 9:20 AM.

It used to be worse (going to bed later, getting up at the same time), but it's gradually getting better. Generally, my sleeping (+ energy levels + mood) is way better when I exercise. Excepting a few weeks rest time + vacation time, I've been doing fairly hardcore exercise 5-7 days a week for soon 4 months.

Ideally I'd go to bed around midnight - 1AM and get up around 7-8 AM -- I'm getting there!
