Not sure what this is, but free is free! Kinda sounds like it comes out of Canada since it mentions a french version and use of the word Chemist instead of Pharmacist.
I actually searched the site...it's like an energy drink for the night when you're partying but it allows you to have a good morning afterward (I'm guessing a hangover suppressant).
Sounds like my friends will want this!
