"Hello everyone! I am home, and so grateful for all your support and well wishes," she wrote. "I am so much better and taking it one day at a time."

Vargas -- who's worked on both the "Today" show and "Good Morning America" -- revealed her whereabouts on Nov. 6 when her absence from the news program became more noticeable to viewers.

"Like so many people, I am dealing with addiction," the anchor said in a statement at the time. "I realized I was becoming increasingly dependent on alcohol. And feel fortunate to have recognized it for the problem it was becoming. I am in treatment and am so thankful for the love and support of my family, friends and colleagues at ABC News. Like so many others, I will deal with this challenge one day at a time. If coming forward today gives one other person the courage to seek help, I’m grateful."

ABC spokesman Jeffrey Schneider also gave his support. "We are proud of the steps Elizabeth has taken and are pulling for her recovery," he said in a statement. "We look forward to having her back home at ABC News, where she has done so much distinguished work over the years. Elizabeth is a member of our family and we will support her in every way we can."

The New Jersey native has been married to "Walking In Memphis" singer-songwriter Marc Cohn since July 2002 and they have two children together, Zachary, 10, and Samuel, 7. She also is a stepmom to Cohn's children Max and Emily, from his previous marriage to Jennifer George.
