I absolutely love coffee, however my body seems to process enzymes slowly. Last time I had non-decaf coffee, I ended up staying up for 24 hrs. I drink decaf now and love how it tastes, but I still get a lot of heartburn from it thanks to that oil that's on coffee beans...
Jamaican coffee is AMAZING. Extremely smooth and terribly delicious. I like my coffee iced since I'm not big on warm drinks.
