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.

Example Input: I tried the product for a few days. It did not help me with any Lucid Dreams at all. I tried it for few days, not every day. Nothing happened. All I got was a headache the next day..like a hangover headache, It tastes bitter like others have mentioned but nothing that I can't handle. The bitterness was no big deal for me.
Example Output: Negative

Example Input: For some reason my husband ordered a TON of this stuff for me for Christmas. We live in Chicago & it's cold so I didn't try it right away. I was craving something sweet so I finally made some tonight. It tastes like icy chocolate, & it's a bit chalky. To be honest it reminds me of the old powdered slimfast. I've got a whole canister and 5 packets of this stuff & I don't know what I'm going to do with it.
Example Output: Negative

Example Input: I first tried this tea at at French restaurant that had ran out of the usual black tea with mint. To my surprise this tea beats any tea (without milk).. no sugar needed. It is naturally sweetened!
Example Output:
Positive
