My first diet soda memory is of the vending machine in the basement of my sorority house in 1972. Diet Doctor Pepper, which I purchased one can at a time to consume while sitting on the floor of somebody’s room or other, playing Yahtzee or Bridge. The empty cans were used for cigarette butts. I would go to the basement before both lunch and dinner, and that was my drink of choice during most meals.
Stay strong and you will survive withdrawal. I'll drink to that...oh WAIT...nevermind.
5-10 cans per day?? Makes my former daily 20 oz. bottle of MD or regular Coke look tame. I, like you, went cold turkey (several years ago). Glad you took the plunge. You will feel better.
