7. Daniel Radcliffe
Harry Potter star Daniel Radcliffe has been sober since he sought treatment for alcoholism in 2013. At the time, he realized drinking was having a negative impact on his health and social life. He started isolating himself, drinking alone in his apartment for days at a time. He blacked out on a regular basis; he began drinking so heavily that, during the last few years of his drinking, he was blacking out nearly every time he drank.
He didn’t like the person he became when he was drinking. He thinks of himself as a fun-loving, respectful person, but drinking made him behave rudely and become boring and antisocial. For a while, concerned friends tried to tell him they thought he might have a problem. Yet, he needed to come to that realization on his own. When he finally admitted to himself that he had a problem with alcohol, he sought treatment to get sober and overcome his addiction.
