I drink between 3-6 8oz cans of red bull daily im 22 and my job is very physical i also don't drink water or eat healthy and i smoke cig am i screwed?

You will be unless..: 5 red bulls have 400 mg of caffeine and 55 grams of sugar. That is a lot of caffeine & sugar & the sugar comes from beets so is likely of gmo origin & best avoided. Smoking cigs is one of the least healthy things you can do. You're young so if you change you'll be ok. Coffee is a better source of caffeine- but not too much. Stop smoking asap. Drink water. Add some healthy foods. See my comment:.
