Input: Consider Input: I bought my mberry pack from mberry.us online hoping to use it to curb my sweet tooth. I followed the directions to the letter, allowing the tablet to dissolve completely on my tongue. I then tried balsalmic vinegar - nothing happened to the taste at all except that my tongue burned a little. So I tried hot sauce - nothing happened again except that my tongue burned a lot. Then I tried regular vinegar - nothing happened again. I even tried taking a second tablet, but it still did nothing but slightly burn my tongue. HUGE waste of money. Super disappointing. DOES NOT WORK!

Output: Negative


Input: Consider Input: I really love these snacks.  They are low in calories and fat while being high in protein, which is important to me because I am a vegetarian.

Output: Positive


Input: Consider Input: Let me begin by saying that I do not like Oreo cookies at all. I think the cookie part is bitter and I hate the white cream filling. When a friend suggested I try these I was reluctant and kept telling her that I was not interested. She insisted so I tried a few and surprisingly did not find them to be bad at all. I'm diabetic, so this is not a snack I will be eating often, but a few here and there won't hurt. If you're expecting these to taste like Oreo cookies (I'm one who's glad they didn't!!), then you'll be disappointed. But if you want a chocolate snack that's low in calories and fat please give these a try.


Output: Positive
