Club soda or seltzer is a good start, if you want the fizz but not the sugar/flavor. If it’s the taste you like, try the syrup they make for fizzy water.
I kicked mine by winning a weight loss bet with a friend. Depression and anxiety caused the weight to come back, but I still haven’t had a soda in three years.
I don’t even boot windows anymore and it still takes over the first boot spot randomly.
