my alarm

Sleeping in my bedroom is is quite possible for me to sleep verrrry late. People probably just think that i oversleep all the time and am a lazy bum bum. But this is totally not true! 

I sleep in the basement of my house & so it is already dead silent down there. Plus my room stays really dark all day! 

If i don't remember to set an alarm it is actually possible for me to sleep until 12 or 1 in the afternoon.
(It's happened frequently)

I don't know how to fix this! But it bothers me because if i don't set my alarm i waste my whole day! 

...Maybe if i went to bed earlier than i would naturally wake up earlier...?

I don't want to put THAT much effort into it though.
