If today fucking sucks because you're tired and haven't slept since your therapist told you that your "addiction" to Ambien was "worrisome", then welcome to the real world. A world that depends on its people consuming copious amounts of coffee (in our case, iced) while trying to pretend like they're not dead inside. But, news flash. According to a recent study, if you're not getting enough sleep, the benefits of one cup of coffee are about the same as multiple ones.
TL;DR: If you haven't really slept in more than three days, seven cups of coffee won't help you anymore than one cup will. So put down that 3rd Trenti cup and kiss any sense of alertness goodbye.
We're all so fucked.
