Anthony McPartlin admitted he nearly died after bingeing on painkillers and alcohol.
The TV presenter has recently left rehab for prescription drug and alcohol abuse following a secret three year battle.
In an exclusive interview with The Sun on Sunday, McPartlin revealed the extent of his turmoil.
He said: "I was at the point where anything — prescription drugs, non-prescription drugs — I would take. And take them with alcohol, which is ridiculous. The doctors told me, 'You could have killed yourself.'"
The I'm A Celebrity co-host praised his wife Lisa for standing by him, despite being difficult to live with.
He lamented: "I've put Lisa through hell with mood swings and depression and how it affects you."
