[Kamog]

The longest number of hours in a row I have slept is about 18 hours. This was when I was a kid and I used to sleep all the time during school holidays when I didn't have very much to do. As long as there was no loud noise and nobody waked me, I'd stay asleep all night and most of the day. This was especially true on cloudy days.

Now, I still sometimes have trouble getting up in the morning in the winter when it's dark or when it's very cloudy, but I have to get up because I have things to do. On weekdays I usually get 6 hours or less of sleep. On weekends, 8 hours.
