How much do you think you drink? Chances are, if you're British, it's too much. We drink like fish on pingers. We're the international alcoholics. We should probably give it a rest. But, for some, the usual routes of drink-curbing just don't work – or maybe leave them too open to "relapse". Luckily, there are currently new ways to stop the boozing being trialled, and one of them involves ketamine.In our new film, Eternal K-Hole of the Spotless Mind, we follow student Timmy Davis as he attempts to lower his alcohol intake with a medically administered ketamine infusion, which messes with the positive associations with alcohol in his head.Can K – the party drug used by crusties and people who think it's coke, but it's not coke, and they quickly find out it's definitely not coke – really be used to treat alcoholism? And if so, what else could it be used to treat?
