Ahh damn.
Well go take a break and take a nap
When i was younger i used to work as a server at a college, but when it would be so dead i would get sleepy as hell, so i would go and sit at a lil sofa thing they had in the bathrooom and close my eyes for about 10 minutes, then i would be good for the rest of the day
U could also have one of those energy drinks,i never liked those thou.
I use to also take sum pills to stay awake when i use to help out workin a night shift at a store.
