Rodriguez joined Lost in its second series

Rodriguez, Anna Lucia in the TV series, was sentenced to five days in jail but spent only 65 hours behind bars.

Time spent in custody after her arrest was taken into account.

Rodriguez is also serving three years' probation after pleading no contest in 2004 in Los Angeles to three traffic violations, including drink-driving.

The actress shared a dormitory with 60 other women while in prison, a spokesman for the jail said.

"I kind of have to get back to my life, go back to making some money," she said outside court after sentencing.

Rodriguez, 27, and co-star Cynthia Watros were arrested within minutes of each other last December on suspicion of driving while under the influence.
