I love this stuff! If there was an option to give as many stars as I wanted, I'd give way more than 5. This is the best thing ever! I tried it back in 2010 when it first came in as a sample and this is the best ever. Better than ibuprofen alone. As soon as I knew I was done drinking for the night, I put this in a big glass of water (its just like alka seltzer; that's how you take this), drank the water after it was fully dissolved and took a couple of ibuprofen with it and went straight to bed. Keep in mind, I was plastered that night. The next morning when I woke up, it was as if nothing happened. The only thing I felt was a little dizzy, as if I were buzzed dizzy but not nearly as bad as buzzed. If anything, it was just a very minor very slight hangover. I had an appetite, I was able to do my normal daily activities without feeling sick or out of it. I HIGHLY RECOMMEND this to everybody.
