I'm an avid coffee drinker and I can't go a day without having my cup of coffee. However, I fear that my habit may be doing more harm than good. Could I be drinking too much coffee? I tend to drink two or three cups of coffee a day. I always have a cup of coffee before heading to work at 7am, then another some time around 12pm. As the day drags out, I feel exhausted and go for a third cup. Am I drinking too much coffee? Is there a healthier pick-me-up that I should turn to? I'd like to kick my habit, but I simply cannot function without it.
