In addition to the drugs and alcohol, Lindsay Lohan is being treated for an addiction to email.

The Machete actress - who voluntarily entered into a substance abuse program at the Betty Ford Clinic in Los Angeles late last month - has reportedly had her phone usage cut, with staff also urging her to reduce the amount of time she spends on social networking websites.

“Lindsay is only allowed to use her phone for two hours a day, and only to keep in touch with family and close friends. Before, she would repeatedly and compulsively email her friends if she was ever in a situation where she felt lonely, and she would vent on Twitter,” a source said.

The policy has been implemented so Lindsay can “concentrate on herself” during therapy. Lindsay is due in court on October 22 for a probation hearing, after she failed two drugs tests last month.
