Let's start with this...
In my opinion caffeine is a like a horrible drug. Many people all over are addicted to it because of how it affects them and makes them energized when they feel low. Little do they know how bad it is because they lead to some health problems like dependence. After drinking caffeine, they slowly start to get addicted to it and their brain becomes reliant on it. If they try to stop drinking it, they will experience fatigue, headaches, anxiety, and other effects and it will even raise blood pressure and cause death if too much is consumed.
