i need alot of sleep, and i mean alot, 11 hours a day is optimum for me. I get 6-7 on school days and 9-11 on weekends, so I am always a little bit tired, this means I can go to sleep when I like, so sometimes I have naps in the evening after school but my mum gets pissed about it so I cant very often, but I love it when I do!
I say hell yes if you can take naps and your tired enough to need on then go ahead!
