I used to drink 2 liter diet sodas everyday, I know the feeling Ria. It was a must to have diet coke with a burger and spaghetti, it just quenches the thirst especially if it was ice cold. One day, just getting my regular physical exam the doctors were alarmed how high my potassium content was. They told me to go to the emergency room so that they can observe my my potassium level was so high. Because of abusing myself with drinking excessive soda, to the point of making it as my water in take, my kidneys were severely affected. Sodas have potassium content. I was confined in the hospital for three days, because of that wake up call, I now drink lemon ( I like calamansi better, but we don’t have it here in NY) and a teaspoon of honey. I am even considering turning into a vegan.
