There are many effects of caffeine to our body. Caffeine in low dose (20-200 mg) as stimulant could keep you stay awake and active, feeling of well-being, increased attention and alertness, increased metabolism rate, but because caffeine is stimulant, it should not used regularly because it could be addictive.

Total of caffeine already consumed is almost 200 mg, this means you are recommended take two cup of coffee a day.

Sometimes, to get rid of these symptoms people add more caffeine. Therefore this cycles will never ends.
