I am always looking for sodas that are healthy to drink. Most diet sodas are just a gimmick. They are still bad to drink and can make you feel bloated. I went to the health food store the other day and found Diet Hansens Soda, so I tried it. I heart it A LOT, especially the Ginger Ale flavor. There are many other flavors that are mostly fruity and delicious.
One thing to note: When combined with certain foods, this soda can taste like you are drinking a Fizzy Candle Stick.
