This fact actually helped me reduce sugar intake through soda. I bought a SodaStream and cut all my soda with carbonated water. After enough time, the diluted soda tastes just as sweet as regular soda used to, and regular soda tastes way too sweet. Sure I'm still drinking it, but my intake is down 1/2 over a day. My other trick was to pick 1 day a week I don't drink or consume any sugar (cuts consumption by 1/7 over a week) and during the month of January I don't consume any either (cuts consumption by 1/12 over a year). I've found these short periods of sugar fasting much easier to get through than completely changing my eating preferences, as most people suggest.
Once you’ve gone without soda for a month, why on earth would you ever go back to drinking it?
Sometimes you get a weak moment that you didn't plan for. I think a lot of us are/will be experiencing this sort of thing post-pandemic; you quit x y or z in lockdown environment but can you keep it up once life gets more chaotic again?
What else am I going to drink with pizza?
No, seriously, you imply that you drink soda at least daily and quite likely several times a day. Once you have quit drinking it, why would you take up such an unhealthy habit again? Sure, have a soda once in a while... but why resume the habitual consumption?
