Some patients swear by it...

We call it ECT Chuck, I once had ECT three times and I didn't even know it because the cunning bastards put me under general anaesthesia. I just had to wipe the jell from my temple and feel a bit of a headache and fuzziness. Then I had a bright idea, tell them you don't want it anymore. Okay they said. Invented by the Nazis who just had to see what happens when you apply an electric shock to try to shock people out of their stupidity, they found it helped. After the war the westerners thought it a good idea too. Some people prefer not to have general anaesthetic. Back in the fifties that wasn't an option, patients were punished with electrocution, for not seeing any light at the end of the tunnel.
