Sounds like you make your Cappuccino quite strong, Silencer. I've been keeping away from the caffeines for a little while, about 3 cups of coffee in the last month (amazing how it affects you without you realizing it).
Favorite beverage at the moment? CALPICO COOLER from the Bubble Tea shop in downtown. They give you a choice of 7 flavors, I like the strawberry flavor with lychee jellies. Anything I've had there, delicious.
Effect: None, unless you consider sugar rush an effect. It's a yogurt beverage, so if you're lactose intolerant, it might have an unhappy effect.
Downside: doesn't last as long as you'd like, even if you get a large one.
