Caffeine is already in plenty of OTC preparations, such as pain relievers and cold medications, but I can see health effects of it that are taken for granted in the coffee cup.

Every day, people use it to wake up. And usually the rule is don't have any after 4pm or so to prevent sleep problems. And with that 70-90% of America statistic, it seems it's a Soma-like drug (reference to Brave New World, not carisoprodol). I think people should be more aware of its potential to create a healthier lifestyle.


It could even be used as an antidepressant. Definitely not for the Major Depressive Disorder that makes you lack serotonin, but maybe for a less serious type. To me, it seems like there are lots of different kinds of depression out there, and caffeine might be able to help with some of them.
I'm putting 100mg in each day of my pill case thingie, and we'll see how my sleeping patterns and mood are. Today already went pretty nicely. I felt like I had a refreshing amount of social energy. I got up at 8:30, then took a 1-2 hour nap around 1pm, which is extremely unusal for me. I usually crash right after class and sleep in until 7-8pm.
