04:30 and it's too late to go to bad have to go up in 3 hours anyway what are some foods to stay awake making coffee right now so don't answer that
Should have gone with the three hours sleep and had the coffee when you woke up. Three hours sleep is way better than none at all, and the caffeine is more effective when you haven't already been on it for the past three hours.
Burn your forearms with a cigarette throughout the day whenever you start feeling drowsy. It works. Before unions, truck drivers used to do that when they were put on 36-48 hour shifts. They don't do it anymore, thanks to Jimmy Hoffa.
