I'm sleeping too much…

I’m sleeping too much. Not vastly too much, but too much. I can’t seem to wake up in the mornings! This morning I was woken up by my flatmate at 9am. Since I was supposed to get to work by 9.30am I had to skip all pleasantries of breakfast and shower, throw my clothes on and throw myself on to the nearest tube train. This isn’t the first time that this has happened recently.
