lack of sleep cause tiredness, tiredness causes you to reach for a cup of coffee, this makes you wired, being tired and wired almost causes me a sort of depressed excitation, where as if i drink coffee when i'm well rested i have an optimistic excitation. Optimistic excitation causes me to focus on the mental world to derive pleasure and pass time, like studying, depressed excitation causes me to want to get material pleasure like eating sugar, or fast food or drinking alcohol to pass time. I ultimately understand that coffee works best in conjunction with good rest, if you caffeinate to power through sleep depravation, you will notice that your ROI is severely diminished and worst of all you will most likely disrupt your sleep the next day. We in the modern world hate listening to our bodies, we try to do all sorts of things to get more out of our day, in the long term this might be the wrong way of looking at things.
