It works but only if you take one or two pills before every drink. I took an entire pack of twenty with a twelve pack of beer over five hours by myself to test it and the side effects were a fairly mild buzz, 12 beers equalled a six pack buzz, and urinating after every drink. The next day I felt a mild headache and a slight upset stomache which lasted for about two hours but was easily fixed with two aspirin and breakfast. My conclusion is; too exspensive and probably too annoying to manage accurately in a social gathering, as well as being just as effective as 12 oz. of water after every drink, which slows down the no. of drinks consumed. My advice; drink less booze and enjoy more reefer!
