We've tested this stuff out like 5 times now. It's pretty great! lol. Seriously, follow the directions and you wake up feeling like you didn't have anything to drink at all! We had a bunch of friends over for several nights over the course of a few weeks, and I'm not too ashamed to admit, I partook a bit more than I should have, and so did the Hubby.Knowing that I had to work the next day, however, I made sure to follow the instructions on the bottle, and I woke up feeling great! A little tired, obviously, but not sick and drained like normal after a night of drinking. I highly recommend this supplement if you know ahead of time that you can't afford the next day hangover.
