  14. Caffeine can cause a slight, temporary rise in heart rate and blood pressure and large doses 

    ●Some interesting facts about caffeine are the effects it has on your body. Over three or four cups of coffee can increase your stress levels and cause lapses in concentration. Drinking up to about three or four cups of instant coffee or a couple of cups of filtered coffee in a day (depending on how strong they are) shouldn't cause most healthy adults any harm, but some people are more sensitive to caffeine than others.

  16. Caffeine can interfere with your sleep

    ●Its effects can vary depending on your metabolism and how much you normally consume but, for most people, if you stay off the caffeine from about six hours before bedtime then you won't be affected.

  18. There's no such thing as caffeine addiction, apparently. 

    ●A fun fact about caffeine is that you may not necessarily have an addiction. Addiction to it would mean that you compulsively consume it against your better judgement, rather than chose to have it by your own free will.
  19. But caffeine dependence is a real thing -
