17. Zac Efron

Zac Efron became a star with the hugely popular Disney Channel movie High School Musical. As his career took off, the young actor started to feel increasingly overwhelmed with the demands of stardom. His work schedule was so chaotic that he no longer had time to be with friends or family, to enjoy his hobbies, or even to relax. He couldn’t even go home because his schedule was so demanding, so he was living from one hotel to the next. He started using drugs and alcohol as a crutch to escape the pressures of daily life. He realized the destructive nature of his dependence on alcohol and drugs. So, he went to rehab, joined Alcoholics Anonymous, and began meeting with a therapist. He made an effort to lead a healthier life and to reconnect with old friends. Since getting sober, he says he’s happier and healthier than ever.
