Is a caffeine thread possible?

[Torvald Von Mansee]

I am not a drinker, nor a consumer of other substances, save one: caffeine.

My favorite means of delivery is in cold beverage form: Coke Zero, Diet Mountain Dew, etc. However, I'm told that this is not good for one's long term health, so I had to switch to other means.

Tea - this is OK. There are many kinds of tea, but not usually my thing.

Coffee - OK, I will sometimes brew coffee before I go to bed at night. I will wake up in the morning and shotgun the lukewarm coffee. I know there are various forms of coffee, but I am not an gourmet on the subject (am I using gourmet properly, here? It seems that it is something which should be reserved for food. Maybe connoisseur is more apt). I used to drink LOOOOOTS of coffee and go to the gym and do leg presses until I got really, really high off of endorphins. That was fun, but could have potentially been fatal.

Anyway, does anyone else have a preference for caffeine over other substances? Or enjoy it at all?
