Low calorie and sugar drinks?

In a can is good too. I can’t do cocktails that I make because if I buy soda for example I have let’s say a sweet tooth and I’ll just down the entire bottle in a day. The diet sodas are no good for me because of that ingredient that studies link it to cancer. Only drinks that comes to mind are white claws or trulys that are 100 calories, I’m not sure about the sugar level though. Anything advice would be awesome
