I absolutely love Coke Zero. I got to the point that I was drinking a 2 liter every day. I started noticing that it was messing with my bladder. I would need to go frequently and urgently. Once I cut out the soda a few years ago, my problem went away. I now drink coffee in the morning and maybe a cup in the late afternoon and home brewed plain black iced tea most of the rest of the day with some water thrown in. I still will occasionally order it if I am out (but as Lilacsforme mentioned upthread, McDonalds no longer carries it and it seems to be getting harder to find) or on vacation. I also buy the fridge packs when we have parties and if there is any leftover I will drink it but once it’s gone that’s it. It doesn’t seem to bother me if I only drink 1-2 on an occasional basis.
