Caffeine buzz killer

Drinking too much coffee not only has a negative impact on your financial wellbeing, it can also affect your mental wellbeing too. The risk of hallucinating increases threefold among heavy coffee drinkers, according to the journal Personality and Individual Differences. Healthy young people who consume more than seven cups of instant coffee a day are three times more likely to hear or see things that were not there. Large amounts of caffeine also makes people think they can sense the presence of ghosts.
