In extreme cases, over-caffeination can even result in death. Intake should be carefully monitored, especially in small children. As caffeine can affect your sleep, it is recommended that you do not drink it after 3 p.m.
What if I want to quit caffeine?
Consuming caffeine can have negative effects and you may be thinking it’s time to quit. If you’ve come to that conclusion, it’s recommended that you don’t try to quit cold turkey. Monitor your caffeine intake and gradually step it down until you eliminate it completely. If you drink caffeine to boost your energy, there are options available so that you don’t lose that boost. Exercise is a good choice which boosts both your energy level and productivity.
If you do quit cold turkey, be prepared to deal with symptoms of caffeine withdrawal. These can include:
- Fatigue, sleepiness, or energy loss
- Anxiety or depression
- Trouble concentrating or being productive
