Task: Sentiment Analysis
Input (English): I've been buying and drinking this for over a year now, and the energy boost is excellent, with a continuous, ~6-hour effect. The most recent shipments seem to have improved the flavor slightly as well, or perhaps I'm getting more used to it. I don't drink it for the flavor, but it's not as heinous as the fake flavors found in the other, non-organic energy shots. 
 Polarity: Positive
Output (English): True
