I'm SO tired!

Lately, sleep has been eluding me. Well, really it's me avoiding it a bit more than it avoiding me. Now right off the bat you might say, "Well then get some more sleep." But that doesn't really work since lately I've been leaving things a little bit late. So I end up having to stay up later than usual to take care of the things that need to get done. Usually this happens only on weekends so my Monday ends up all messed up because I'm running on 1-2 hours of rest. So then while really tired, I tend to try to make up for lost time on breaks and essentially any chance I get. This backfires because I end up not feeling tired when bedtime rolls around. So I stay up a little later and suffer the consequences the next day. This pattern continues until the weekend. I really need to do something about my inability to focus and do my work.
