On the way to a gig....

I am about to jump onto a train heading to a gig pretty far away.

I have been nonstop since 6am this morning for several reasons. It's 11am now. The time is passing soooo slowly today. I have a full day ahead and don't know if I can go like this till 9pm. I know this pattern. I will be exhausted even before the gig starts and my head will be almost exploding! I can foresee myself in five hours.
