when sleep is no longer a waste of time

I’m having trouble sleeping. As much as I want to, it seems that an 8 hour sleep is just a pigment of my imagination. Everything seems coming back to me. Maybe I have overused myself for the past couple of years that it’s catching up. “Sleep is a waste of time”, a line taken from the movie Gladiator (i think) that I have taken into practice. There was a time when I was attending review classes for 6 hours and working 9 hours a day, also had 2 jobs at the same time and lately I been working more than 40 hours a week. Is this the repercussion of the things I have done?

As science would put it, in a very action there’s a reaction (something like that). I’ve done the action, just waiting for my body’s reaction.

One thing is certain, I really need to take a break from all of this or this would just break me in the future… with how things are going…. It’s seems that it is a very near future.
