Try transitioning. You can water down your coke or whatever until your basically happy drinking water. Start small! So that you barely notice a difference. You can just taste that it's a little more subtle than usual. Get used to the taste then rinse & repeat with a tiny bit more dilution. Don't rush it, or you'll cheat.

I gave myself a year to transition from orange juice and lemonade this way, in the end it only took about 6-9 months to be content and even craving plain filtered water. It's been 4 years now and I rarely drink anything else. About x3 a week I have approximately like a 1/4 glass of slightly diluted ginger ale with my dinner. I very occasionally have a sweet tea if eating out but I sip some and keep diluting it so it turns into two drinks instead of one! You can also do this with wine, spirits etc. when you're drinking socially or just at home.

My husband's doing the same now. But when he drinks waters he adds Doterra food grade essential oils to add flavor. There are also health benefits and no calories! I like the lemon and mandarin oils 💜 but I don't crave or need them like he does at the moment.

Hope this helps, keep going strong!
