"There's this whole culture of competition that sucks people in" with online gaming, said Heidrich, now a father of two. "People do it at the expense of everything that was a constant in their lives." Heidrich now visits websites that discuss gaming addiction regularly "to remind myself to keep my love for online games in check."

　　Toebe also regularly visits a site where posters discuss Internet overuse. In August, when she first realized she had a problem, she posted a message on a Yahoo Internet addiction group with the subject line: "I have an Internet Addiction."

　　"I'm self-employed and need the Internet for my work, but I'm failing to accomplish my work,to take care of my home, to give attention to my children," she wrote in a message sent to the group."I have no money or insurance to get professional help; I can't even pay my mortgage (抵押贷款) and face losing everything."

　　Since then, Toebe said, she has kept her promise to herself to cut back on her Internet use. "I have a boyfriend now, and I'm not interested in online dating," she said by phone last week. "It's a lot better now."
