in reply to My preferred source of caffeine is...

Kahlua has caffeine, right? I switched to Kahlua during the heat of summer because I can drink it iced. Unfortunately, I think I'm developing a caffeine allergy with some weird symptoms. After 5 or 6 cups, I have trouble walking, but I'm a great dancer.

OK, disregard the above paragraph. Seriously, it's cafe con leche for me. Two years of working in a coffee shop tore my stomach up, so no more strong drinks for me. I need something that's gentle on my tummy.
