Los Angeles, Actor Zac Efron, who checked into treatment facilities twice last year to get help for rumoured substance abuse and alcoholism, says he found going to rehab "interesting".
"I am so happy now and I feel like I am in a great place. It was an interesting year and I learnt so many things.
"But the best part of it was being able to reflect upon my experiences and what I had learnt about myself and the kind of man I want to be," femalefirst.co.uk quoted the 26-year-old as saying.
