Query: Counter-productive effect - Bad service

I ordered this product on a Wednesday, needed it for Sunday, and paid $14.95 for rush shipping. I then immediately emailed them asking them to expedite the order, especially since I paid so much for shipping a tiny item. I recevied a response over 24 hours later informing me that I would receive the product on Monday, 5 days after my order, AKA standard delivery time.My next performance, I kept myself hydrated the day I had to sing, and used this as a supplement to hopefully prevent the random coughing fits I get from my nerves drying out my throat. It tasted like sugar water, and had the effect of causing me to cough MORE than usual, rendering the product useless and counter-productive.Would NOT recommend.
