I used to be able to sleep really late when I was younger and will still function well during the day.
But that's the key word: younger days. I'm certainly not young anymore.
I was running around a lot on Friday night driving everyone here and there (using my parent's car since mine is in the shops) and I came home quite late.
My sleeping pattern went berserk as a result.
Sleeping at 3:30am till 9:00am.
Then 5:20pm till 1:25am and 3:50am to 7:40am.
And 9:10pm to 7:00am.
I seem to have enough hours of sleep but why do I still feel so tired?
