I think it’s a combination of flavor and dopamine from drinking it. A lot of Diet Coke drinkers would rather drink water than Diet Pepsi. Not that it taste “bad”, it’s just not what they’re craving.
I don’t/borderline can’t drink coffee. I’ve made a lot of dietary and activity chnages in the past couple years but the mainstay has been diet or Pepsi max.
I’ve straight told people it’s just gonna have to be my vice. I can eat salads and peanut butter sandwiches all day and night. But i haven’t found a way to wean myself from caffeine.
I definitely don’t like when I drink too much (see coffee comment). But I can’t just cold turkey it either.
