At the same time, Mueller checked into a separate rehab center, but left a few days later after her counselors agreed she was fit to live at home as long as experts monitored her.
Mueller was charged with a DUI in 1996 and cocaine possession in 2001.
Sheen's latest troubles stem from a Christmas Eve spat that turned ugly during the early hours of Dec. 25.
In an audio recording of a 911 call, a woman who identifies herself as Mueller tells the dispatcher that her husband threatened her with a knife and added, "I thought I was going to die for one hour."
"My husband had me with a knife," she told the 911 operator. " I was scared for my life and he threatened me." She described the knife as a "switchblade."
When asked her husband's name, she waits before admitting "It's Charlie Sheen," and starts crying.
The actor was arrested and spent the better part of Christmas Day in jail. After posting an $8,500 bond, Sheen was released from jail that evening.
