Personally, I have stopped drinking soda totally.
However, for a vegetarian, it's hard to avoid sugars, overall carbohydrates, gluten, etc.
I ate one month gluten free. It was livable, but not a lot of fun and choice. Overall, I now try to limit gluten but I don't totally eliminate it.
In terms of sugar, I still eat too much I think: chocolate mostly, dried cranberries (with sugar).
