Mixing energy drinks with alcohol is common but dangerous. The stimulating effects of caffeine can mask the depressant effects of alcohol, leading to risky behaviour and alcohol poisoning.

While energy drinks can provide a temporary energy boost, excessive consumption can harm health. It is advisable not to exceed the total caffeine intake of 300mg daily from tea, coffee, energy drinks, pre-workouts, and other caffeinated foods and beverages.
