If my pee smells like coffee, am i drinking too much?

Of something, yes.: Pee is filtered blood, and the smell of pee reflects what has been in the blood lately. If your pee smells strongly - period - then you don't have enough water in your body and need to drink lots more. The exact smell of pee was used for years to determine what infection someone's body had. Coffee-smell in the kitchen is good, but in the bathroom it means you need medicine. Go see your doc.
