Your heart is racing
The feeling that your heart is beating too fast can be frightening. It may feel like your heart is trying to escape from your ribcage. According to WebMD, these heart palpitations are often caused by the consumption of caffeine, nicotine, and even alcohol. In some cases, a racing heart can lead to dizziness and even fainting spells. Sadly, one of the only solutions to getting rid of constant heart palpitations is to avoid caffeine altogether.
