The 41-year-old I’m A Celebrity…Get Me Out Of Here! presenter finished his two-month rehab stint on Friday and is now clean of all drugs except paracetamol.
“I was given an envelope,” he told The Sun. “It was a handwritten note from Harry sending all of his best wishes on behalf of him, William and Catherine and telling me well done for speaking out.
“Obviously he leads the Heads Together charity, so it’s something he encourages,” Ant continued, adding: “I wish I’d spoken out a lot earlier. But what a great time to get that letter. Brilliant. Thanks Haz.”
“I was at the point where anything – prescription drugs, non-prescription drugs – I would take,” he confessed, saying that he would also combine the cocktail of pain medication with alcohol, a potentially fatal combination.
“The doctors told me, ‘You could have killed yourself,'” he added, recalling an incident where a binge led to him being rushed to hospital.
