We can't ignore the energy boost and mental alertness that comes from coffee but we can't forget the caffeine addiction that also comes as a part and parcel of coffee towards a negative side. Most of the people who consume coffee regularly, even by drinking just one caffeine laced soda or a small cup of coffee daily, develop a mild addiction to caffeine. Some doctors call caffeine addiction a cause of serious concern while the others call caffeine addiction a "mild" form of addiction that isn't half as difficult to do away with compared to the other forms of addictions.
