Task: Sentiment Analysis
Input (English): I can't believe I didn't check out the ingredients for this.  I never would have bought it if I would have known there was artificial sweetener in it!  First cup though, I got that weird after taste it gives and that was all she wrote.  If you don't have a problem with a chemical taste or concerns about health problems, you may like it.  Not worth it to us. 
 Polarity: Negative
Output (English): True
