I used to drink 4x 44oz regular sodas per day back in high school and college. I worked so many hours on my feet that I burned it off so i never saw the consequences. I then started noticing that all the people joining me at the gas station soda machine were morbidly obese individuals that looked like Mammy Tornado and had huge FUPAs. It started to come together for me that this would be me in a few years.
Completely cut out soda after that. Now, as this comment said, I only drink it when mixed with whiskey. That's literally it. I can't even drink regular soda anymore, had to switch to diet. I should rightfully have died or gotten the Beetis from how much sugar I drank back then. Water tastes so much better.
