Instruct: Classify Amazon reviews into positive or negative sentiment
Query: not tired

sometimes i don't understand the good reviews some products get, i just took one of these pills, put it under my tongue over an hour ago, it is 3 am now and i am more awake than when i took it, more money i wasted, needed tea spoons so i bought a whole flatware set, tea spoons not a regular size teaspoon, rag you wet and shake to keep you cool, just a wet rag, hair clippers, blade dull doesn't even cut after one day, not really blaming amazon, but out of 100 things i bought over last 3 years, i have thrown away half, that were total garbage.
