Another person here that totally depends on what I’m doing.
Currently my sleeping pattern is all to pot, couple of VERY late nights last week trying to get coursework done in time for a deadline. When it’s more in tune though, 7:45ish on the days I have lectures, anywhere between 8 and 12 on the other days depending on what I can be arsed to do, and erm… Well yeah. Don’t have a job once again (as well as being a student), so have become a little lazy again.
When I was with my ex GF, I was definitely one of those that would struggle like hell to get up for 7am on the weekdays to go to work, but then come the weekend, and time to do things I wanted to do, I had no problems getting up where she would be wanting a lie in!
