Michelle Rodriguez fears her career may be over now that she faces jail on DUI charges.

The sacked Lost actress - who has committed a string of traffic-related offences including hit-and-run and driving while under the influence of alcohol - was sentenced to 180 days in prison after lying about completing community service.

Michelle has posted a letter to fans expressing her concern that her excessive lifestyle may have jeopardised her future in Hollywood.

She writes, "When I moved here to Hollywood, California four years ago....excess became my only remedy. Yeah, it took me a lot of falls to wake up, breathe, and appreciate again.

"I have reached the end of my rope with regards to my career. It has taken me two years to slow down and pay attention."

Michelle must report to a Los Angeles County jail to begin her sentence by 24 December.

She recently submitted herself to a drugs test to prove to the media that she doesn't have a cocaine problem.
