Prince Harry made two appearances on American television to discuss his highly anticipated memoir, Spare, which is scheduled for publication Tuesday by Random House.

The royal was interviewed by Anderson Cooper on 60 Minutes Sunday night, and discussed the revelation in his book that he used psychedelic-assisted therapy to help address the trauma he experienced after the death of his mother, Princess Diana, in 1997.

“I would never recommend people to do this recreationally,” Harry said. “But doing it with the right people if you are suffering from a huge amount of loss, grief or trauma, then these things have a way of working as a medicine.”

He also discussed the reaction of unnamed family members to his marriage to Meghan Markle.

“A large part of it for the family, but also the British press and numerous other people is, like, ‘He’s changed. She must be a witch. He’s changed,’” Harry said. “As opposed to yeah, I did change, and I’m really glad I changed. Because rather than getting drunk, falling out of clubs, taking drugs, I had now found the love of my life, and I now had the opportunity to start a family with her.”

Harry also talked about his book with Michael Strahan on Good Morning America on Monday, addressing his family’s reaction to the memoir.

“I have thought about it long and hard,” he said. "And as far as I see it, the divide couldn’t be greater [than] before this book."

He said he hopes to reconcile with his older brother, Prince William, with whom he has a famously strained relationship.

“I hope that we will be joined at the hip again,” he said. “Because, you know, if there’s something that will terrify the British press more than anything, it’s William and I being aligned.”
