"Brooke was uncomfortable with the way Adderall was making her behave," her attorney, Yale Galanter, tells TMZ. "Brooke continues her lifelong battle with drug addiction by taking these steps herself to prevent a further drug relapse."
According to the site, Mueller overdosed on the psycho-stimulant last week. The Adderall pills were a prescription, and Galanter claims his client had no illegal drugs in her system when she entered the hospital. At the time, it was reported that she was diagnosed with dehydration and exhaustion.
Prior to this incident, Mueller entered rehab over the summer after experiencing a relapse in her crack-cocaine addiction. The 34-year-old mother of twins Max and Bob, both 3, also entered rehab in 2010 and three times in 2011.
"After further reflection and consideration, Brooke has decided to remove herself from the media spotlight and has entered a long-term, in-patient treatment center where she can focus on her recovery without distraction," Mueller's spokesperson Steve Honig said in a statement released in Dec. 2011. "Brooke's goal is to maintain her sobriety, and she believes this is the best option to reach that goal."
