I've recently discovered the joys off coffee and it's not become pretty much essential at keep me awake and functioning during the day.
I am, however, a bit worried that I drink too much! I usually stick to no more than 3, maybe occasionally 4 if I'm feeling particularly tired but I'm wondering if this is still too much? I don't want to end up addicted and with withdrawal symptoms if I don't have any one day!
How much is too much?
