Chemists are taking advantage of today’s spike in Christmas-party hangovers by charging dull-eyed customers up to $300 for a single tablet of Berocca.

One office worker who has yet to go to bed after enjoying “a few beers” at his Christmas party, which began yesterday morning and continued on into the afternoon, evening and then morning again, said he was being exploited by his local pharmacy.

“They’re the worst type of drug dealers,” the bloody-nosed man said. “But with my only other option being cutting my head off to dull the pain, I had to pay up.”

Another office workers who overdid things by a Penrith mile said he refused to pay his legal drug dealer for the mild relief.

“I’m just going to keep drinking and never stop,” he said. “That way I’ll never have a hangover again.”

Shares in Berocca tablets are set to rival the rise of cryptocurrency Bitcoin, according to early reports.
