Example Input: I love this candy. After weight watchers I had to cut back but still have a craving for it.
Example Output: 5

Example Input: After reading all the great reviews, I optimistically ordered some of this tea. I've had problems with sinus congestion very often this winter and have tried all kinds of remedies with little success. Unfortunately, this really didn't do anything for me. The taste is OK (bearable), but it did nothing to relieve my sinus congestion. (So far the only things I've found that have helped me somewhat are the Vicks personal warm mist humidifier and Neti Xlear)
Example Output: 2

Example Input: It's very nice that the company put 100 calories packages out--great marketing idea. They taste okay to me. A bit subtle on the chocolate IHMO. Mostly they're lightly-flavored, chocolate, wheat crackers. They have very little nutritional value but over 39% sugar. The 100 calories is achieved by a very light product--it doesn't weigh much. So, 100 calories sounds great--but only if you eat but one package. Not easy to do if you're hungry. Still, it's a convenient snack to put in a backpack, lunch box, carry-on (now that they don't feed you much when you fly), etc. with less calories than most alternatives. Could also tide you over between meals. Still, I'd personally prefer something a bit healthier. But that's why there's chocolate & vanilla--oops, they left out the vanilla!
