Yeah, I don't have insomnia one bit, so I'm never awake in the night, unless you count evening/primetime as night haha
I used to pull all-nighters during the summer between my high school freshman and sophomore years, staying up until 4:30 through 5am at times. I guess it just died down for me after a long while, because the latest I go to bed nowadays is usually between 1am and 1:30am
