how bad is drinking 3 cocacola soda cans everyday?!

It's not only the sugar that's the issue, but also the caffeine and other ingredients. http://www.wisebread.com/51-uses-for-coca-cola-the-ultimate-list check this out, and then decide if you still want to drink that much of it. It's not horrid in moderation, but do you really want to drink three cans of something that can de-rust something? Water is the ultimate drink. It helps you think, cures headaches and tiredness, and just generally helps your body function properly

Trust me, stop right now. Each can has around 40g of sugar and the recommended amount to not go over is 40. So you're taking in at least 120g a day, plus your other foods, so you're way over the limit. Stop right now unless you want diabetes in the future.

alot of sugar is entering your body, lol like at least 90 grams a day plus your other foods, so i would for your sake cut back at least one can, I dont drink soda period lol and if u contuine you might get high chelosteral

I heard that some people used coca cola to clean toilets. Because its so strong . I like it myself but i drink it once a couple months.

It f's around with your ticker. Bad for you in the long run.
