In 1993 Richard Bentall went a bit mad.
He voluntarily took an antipsychotic drug and at first thought he'd get through unscathed.
"For the first hour I didn't feel too bad. I thought maybe this is okay. I can get away with this. I felt a bit light-headed."
Then somebody asked him to fill in a form. "I looked at this test and I couldn't have filled it in to save my life. It would have been easier to climb Mt Everest."
That was the least of his troubles. Bentall, an expert on psychosis from the University of Bangor in Wales who is in New Zealand under the University of Auckland Hood Fellowship programme, developed akathisia - unpleasant sensations of inner restlessness and an inability to sit still.
"It was accompanied by a feeling that I couldn't do anything, which is really distressing. I felt profoundly depressed. They tried to persuade me to do these cognitive tests on the computer and I just started crying."
Volunteers were given either 5mg of the antipsychotic droperidol, 1mg of lorazepam, a type of tranquillizer, or a placebo.
"The experiment completely failed," says Bentall. "Because first, it's absolutely mind-bogglingly obvious to anybody after an hour whether or not they are taking an antipsychotic or a placebo - the side effects are so marked. There is no such thing as a placebo antipsychotic in that sense."
But it was the fact that most of the healthy volunteers who took the antipsychotic became so unwell, let alone do the cognitive tests, that meant the study couldn't continue. One psychiatrist became suicidal and had to be put under observation.
In his controversial book Let Them Eat Prozac Healy wrote about what the volunteers experienced. "It was not like anything that had happened to them before... Highly personal memories of previous unhappy times - broken relationships or loneliness - seemed to be flooding back. And if they previously held themselves responsible for these unhappy times, they seemed to hold themselves responsible for feeling the way they did now as well."
