As best as I can tell, I've developed a healthy immunity to the supposed effects of caffeine.
I don't think I've ever had a caffeine high. Now, my only source of caffeine is Coke and Cherry Pepsi (and the very occasional Dew), so that may be a factor. However, I was at a point in university where I was consuming a few litres a day of Coca-Cola.
Heck, I think I need the caffeine simply to function normally now (says the man who just went out to buy a 12-pack a couple of hours ago, after being cola-free for a hellish 24 hours) |
