When I first saw thisoffer, I thought they were going to send me an actual drinking mate. Score, a new friend! Then I realized they were just anti-hangover tablets.
To be honest, I'm always weary of over-the-counter remedies like this. Isn't a hangover simply caused by not having enough livers? Just have a few extra ones installed like I did and you'll be all set to drink as much as you want. You'd be amazed at what you can buy on the black market these days!
