Too Much Caffeine

Caffeine is a central nervous system stimulant which temporarily wards off drowsiness and restores alertness. We all know that too much of this is not good to the body. I am a coffee and tea lover and I take at least 2 mugs of coffee everyday. I am not much into drinking soda but I like the taste of citrus soda. I never realized that it contains more caffeine than the regular soda until I came upon one article in the newspaper. I thought citrus soda has lesser caffeine content.
