I haven't been drinking much canned coffee for a while, maybe because I've heard people ask the following questions about coffee:
Can coffee cause headache?

Can coffee help you lose weight?
Can coffee help you gain weight?
Can coffee make you fat?
Can coffee make you tired?
Can coffee make you sleepy?
Can coffee stunt growth?
and another dreaded one........... Can coffee kill you!?
