Others have mentioned it but I want to double down! I was addicted to soda from 13-25 and I have lost a lot of teeth because of it. Sodastream helped me kick it. It’s much cheaper to maintain and using less acidic waters since you can just use your tap water (or whatever water you want) and has zero sugar. I buy liquid water flavors from Aldi that use stevia for sweetening. 100% the bubbles and they can taste a lot more than the la croix stuff. Put in as much or little flavor as you want. Combine dark cherry and vanilla for a pretty good cola taste too. Zero calories, no gunk on teeth, cost about $22 USD to maintain carbonation of the sodastream and I drink like 2-5 liters of the stuff a day. Good luck! Sugar is one of the hardest addictions out there and big cola makes sure the alternatives are expensive or taste bad. You can do this! The effects of that acidic soda and water on your body overtime does nothing but DAMAGE. love yourself!
Seconding this. A lot of the flavors have food dyes but you can also find stevia and more “natural” colored flavors at aldis and other stores, as well!
