Anyone having sleep problems?

I don't have sleep issues at all, but I have noticed that there are some life rhythms that don't work for me.

I need to sleep 7 to 8 hours, but I don't like to get up too late in the morning and to stay up late at night. The reason is very simple: if I get up early, I can achieve much more than staying up late.

For me, anything past 11 PM becomes late. I am happy if I can get up at 6 AM, although I must confess that lately I have been getting up at 8 AM or later, which is awfully late in my book.

For my work, I sometimes go to bed at 2 AM. As I need to concentrate, the noise around me, the people awoken doing their stuff, talking, calling, emailing messaging me... they disrupt my work. At night, I am 'alone' and I can concentrate better. However, my performance hold only for a limited time, and definitely I can pull off a stunt like this once in a while, but not regularly.

I was never the kind of person who can pull an all nighter, and I did it only once or twice in my life because I had to and not because I wanted to.

I am also one of those lucky persons who recline their airplane seat and call it a day for several hours in a row. Last time I boarded a plane, I was asleep before they started distributing the food.
