Listen to Aerosmith on iHeartRadio

Steven Tyler admits he has to put an effort into maintaining his sobriety.  But the Aerosmith frontman tells "The Dr. Oz Show" one of the biggest challenges he faces comes from the people who are supposed to be helping him stay healthy. 

Tyler says he "lost everything" to his addictions, and admits "it's serious when you lose your kids, your children, your wife, your band, your job and you’ll never understand why because you're an addict." 

But he says he's now been sober three years.  The rocker explains that he had 12 years of sobriety to his credit when he experienced a relapse - for which he's taking the blame. 

Steven admits he "simply didn't follow" his program while recovering from a series of operations and kept his medication at his bedside, and as a result he started taking more than his prescribed dose.  Tyler adds that he's "a very good drug addict" because he's "done it for so many years."
