A lawyer for drug lord Joaquin "El Chapo" Guzman says his client now wants to be extradited as soon as possible to the United States. He complains that guards at a Mexican maximum-security prison won't let him sleep.

Lawyer Jose Refugio Rodriguez says Guzman told him to negotiate with U.S. authorities for a lighter sentence and confinement at a medium-security prison.

Rodriguez told the Radio Formula station Wednesday he talked to Guzman Tuesday at the Altiplano prison west of Mexico City.

Guzman's lawyers once vowed to fight extradition, and officials said it would take at least a year.

But Rodriguez suggested it could be done in two months.

Guards wake Guzman every four hours for a head count. He escaped the prison in July and was recaptured in January.
