One of the ways I cut back was to have water sitting next to my soda for the first few months. Just have water right next to it. I would always make sure it was fresh, cold water with ice if possible. I would alternate between them so I was getting more water, but also so I could get used to the taste again.
Now, if I ever have a sweet drink, I follow it up with a glass of water after. Even if you just balance it between the two, itβs better than drinking only soda. Moderation is better than nothing at all.
