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?
