I agree. The latest I go to bed now is 9:30pm and by the time it's 2am, I feel well rested. I fall back asleep though and feel groggy at 6am and don't want to wake up. Weird...

@introvert-dime, really? I never knew those hours are important. But i'll like to know the reason for that though.
@best gift, thanks for educating us on the importance of sleep. I think another way one can improve sleep habits is getting rid of worries and anxieties. I personally find it hard to sleep when I am worried

These hours are very important to sleep because at that time body goes through increase in melatonin production which is associated with the metabolic activities of our body.

I usually wake up right after 2a.m. every night. Usually go to sleep for a couple more hours.
