I really appreciate your desire to quit using coke.
I am also a big coke drinker, when I was in high school I drank 6 liters of coke a day, a few years ago I reduced the amount to 1.5 liters a day.
I didn't drink water at all, only juice.
Do you know what the result of this lifestyle has been?
I had three kidney operations, because all the time, because of the high amount of sugar, I was getting kidney stones.
And now I'm addicted to coke, I keep trying to quit and I have terrible headaches.
But I'm not giving up, I'll try to reduce the amount every day, maybe one day I won't drink at all.
