tomato bisque soup

I was making this tomato bisque and the recipe called for 1 cup sugar so I thought I added 1 cup of sugar, but what I added was 1 cup of truvia, an artificial sweetener so my 1 cup of sugar is really 2 cups of sugar. I have added 3 cans more of diced tomatoes plus some dill even a can of tomato sauce. There is 1 quart of half and half and 1 quart of heavy cream. HELP ME IT TOO SWEET!!!!!SOUP
