Consuming too much caffeine can irritate your stomach and cause nausea and vomiting. This is more likely to occur if you’re consuming caffeine on an empty stomach.

Caffeine is a diuretic, which means it can increase urination and lead to dehydration. If you’re consuming caffeine regularly, it’s important to drink plenty of water to stay hydrated.

To prevent caffeine overdose, it’s important to monitor your intake and be aware of the caffeine content in the foods and drinks you consume. Here are some tips to help you prevent caffeine overdose:
