In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
One example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Solution is here: negative
Explanation: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

Now, solve this: The day I started taking this I encountered painful gastrointestinal symptoms, but kept taking it, thinking it was a coincidence. After 4 days of discomfort concluding with a missed day of work, I finally stopped and switched to the other product marketed to this demographic, and the symptoms went away. I don't know if it was just coincidence or if this product had the opposite effect intended on me, but one other commenter said the same thing, so I wonder if one of the ingredients is problematic for some people. I'd like to experiment to find out if it was just coincidence, but I don't want to feel that way again and will stay with the competition.
Solution:
negative
