How much coke is too much coke?

1 serving more than once a week is too much health wise. It's only got 34mg in 355ml of cola 6oz of coffee has 80-200mg 1 shot of espresso has 29-100mg etc, etc. normally up to 300mg a day is safe though. so if I remember right, 1ltr is 1000mls so you drink about 1500 mls which is about 145mg of caffeine so you're fine caffeine wise. not so much sugar, calorie, health wise.

Well i think you can drink about 2 litres but i dont think you would be very goood after

Uh just don't drink a lot of coke

A glass.

People tend to overestimate the caffeine content of sodas. People drink too much soda thinking they're being affected by the caffeine, when in fact, it's the sugar content that's making them feel weird or experience cravings. Coca-Cola Classic contains 35mg of caffeine per 12 ounces. It's about the same content in diet and zero versions. 1.5 liters is about 51 ounces, at 2.9 mg caffeine in Coke per ounce, you're looking at an intake of 148 mg of caffeine in 1.5 liters of Coke. But it sounds you drank this over the course of a day and your body processes caffeine fairly efficiently. But lets just say, for simplicity, that you drank 1.5 liters of Coke - totaling 148 mg caffeine - in about 1 hour. I drink coffee regularly - 8 oz of brewed coffee is about 110 mg of caffeine. If i drink just one small cup of coffee, I've already had almost the same amount of caffeine you have in 1.5 liters of coke. I regularly drink two cups of coffee and I know I drink more than 8 oz at a time. I'd say I regularly drink over 250 mg of caffeine every, single morning. Sometimes more. Already we're way off numbers wise - as you can clearly see, compared to coffee, Coke (and most other non-energy sodas, including Mountain Dew) do not contain much caffeine. Experts agree, that for most healthy adults, 200-300 mg of caffeine per day is perfectly healthy. You'd probably have to drink about 3 liters of Coke before you're having too much caffeine - but over 300 mg isn't really going to hurt you, it'll probably just make you uncomfortable and you shouldn't drink that much regularly. The problem with you drinking 3 liters of Coke would be the sugar and calories. That's somewhere in the neighborhood of 1000 calories worth of sugar. Short answer? You probably won't drink enough Coke or any soda to be drinking too much caffeine. But you should carefully consider the sugar and caloric content as these things are far more harmful to your body (and teeth) than the caffeine. While diet and zero versions of coke have no sugar or calories, they do have a reasonable sodium content. Now if you drank the same amount of energy drink, which can contain up to 250 mg caffeine per can, just two cans can be too much caffeine and that's not to mention the very high sugar content.
