Senator David Norris has not had an unbroken night's sleep since his failed bid for the presidency, he said last night.
Speaking on RTE's Late Late Show, he spoke of his experience of a very bruising campaign which proved very rough on himself and people close to him.
He said he had spent €400,000 on his presidential bid and most of the money had come out of his own pocket. As a result, he had lost his entire life savings.
He still owes a large amount of money to the banks but he had succeeded in getting his bank debt down to below €100,000.
However, he said he did not regret entering the campaign. And he was delighted President Michael D Higgins was doing a marvellous job, especially during his current presidential trip to South America.
He said people working in the media had been engaged in a 'monstering' attack on him which meant that "the most malign construction" was placed on whatever he did.
He said he would welcome an opportunity to give evidence to an inquiry into the behaviour of the media.
He said his new book, A Kick Against The Pricks, was an exciting and very funny account of his very eventful life and he would be using its proceeds to help pay some of his bank debts.
Elsewhere on last night's show, author Cecelia Ahern told how she was eating healthily -- thanks to her father Bertie's prowess at growing vegetables.
She told Ryan Tubridy her goal of healthy eating has been achieved since the former taoiseach has begun growing vegetables on an family allotment. And husband David tends to the herbs, she said.
She added that she writes all her books in longhand and always replies personally to those who send her letters.
