Ah, a little tired you say? Get a fucking fact check. Get used enough to coffee and you basically won't be able to wake up properly, get headaches, nausea, bad temper and other symptoms without your dose.
I am comparing different substances as being beneficial when used in small amounts while getting drastically to the worse when consumed regularly or without moderation. In this kind of a comparison it doesn't really matter if I compare cocaine and fapping off. If you can't comprehend this, I am not going to continue talking to you - as your IQ wouldn't pass a bar buried in bedrock.
