Celebrities Who Were Addicted

At the beginning of her career, Adele used to worry a lot about how she looked onstage. To gain courage, she started to drink before her shows. Gradually, this habit turned into a real problem. In 2009, Adele decided to kick her habit because hangovers were beginning to affect her voice and cause her to oversleep on concert days. Following ligament surgery, the singer stopped drinking and is now leading a healthy lifestyle.
