I myself have never consumed as much as one sip of coffee. The smell of it alone is enough to make me gag. However, I do enjoy mocha flavored food, as long as it isn't too strong. 31 Flavors makes a killer mocha shake.
I prefer to ingest my caffeine by way of soda pop. Sometimes diet Coke and sometimes regular Pepsi. It's cold, it's refreshing and it's a much more effective waker-upper than a hot beverage. About the only hot things I drink are apple cider and hot chocolate. Both of them make me want to go back to bed and get under the covers.
Just my two cents.
