New beer keeps me awake at nights

So someone has invented a beer which contains caffeine.

Anheuser-Busch is launching its caffeinated beer in the UK. BE (Beer With Extra) contains 5% alcohol, 60.4mg of caffeine, guarana, and ginseng. In the US, BE is sold as B-to-the-E (BE).

No chance of falling asleep after a beer now.
