Brian Conley has revealed he was forced to quit I'm A Celebrity...Get Me Out Of Here! after suffering from the effects of malnutrition and exhaustion.
The 51-year-old entertainer also admitted he stopped taking anti-depressants he had used for 15 years during filming in the Australian jungle, against the wishes of the show's producers.
Speaking to ITV's Daybreak, the funnyman said: "They said if I did not comply with these regulations then I would not be on the show.
"It is under extreme circumstances and I started to feel really bad because in the end, very shortly after that, I did have to leave.
"I had an examination and they found out I had malnutrition and I was suffering from exhaustion. They sedated me in hospital and gave me a tablet that would probably knock out a horse for two days. I woke up with a saline drip in my arm thinking, 'what on earth has happened here?'
"I'm lying in hospital being heavily sedated with a saline drip because I suffer from malnutrition and exhaustion, all because of a lovely, fluffy show that Ant and Dec do.
"I can tell you it's not fluffy out there, it's the real world."
Brian, who spent 10 days in the jungle, said he had not taken anti-depressants since leaving the show but admitted producers were right to insist that he take the medication.
"It's made me a much stronger man and you're looking at someone who doesn't need anti-depressants. I realise that now," he said. "ITV is a big huge company, they have got to do it right and if I've brought these tablets in, I've got to take them."
Pop star Limahl was the second contestant to be evicted from the jungle, after Tory MP Nadine Dorries was the first to be voted out by the public.
