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?

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?
