A Berocca a pinkish tablet about the diameter of a mouse ball. Dissolved in water, Berocca becomes a red fizzy liquid which tastes a kinda sorta like orange juice, although there are a few flavours available.

Berocca is particularly popular as a hangover cure, although I'm not sure it helps. According to the packaging, if you "smoke too much, work too hard, drink too much, or don't get enough sleep, you may not be getting enough Vitamin B." I don't know if this is a case of cause and effect or just a coincidence.

I've been told that you can only get Berocca in Australia, so I took a shitload with me when I left Sydney two months ago. So far my supply hasn't run out, so I haven't tested that claim.

Thanks for the tip Heyoka, but I must point out out that it seems you can get Berocca from almost every chemist except Boots. Instead of Berocca, they stock Boots Effervescant Vitamin C tablets.
