Actor Tom Sizemore wanted to kill himself because of his drug addiction. Sizemore, sentenced to 17 months in jail and four months in drug treatment for repeatedly failing drug tests while on probation on March 25, 2005, revealed his brain was so messed up by the drugs, that he contemplated suicide one night, when he couldn't remember where he lived.

He tells news show Extra: "I couldn't remember where I lived. I was going to kill myself... I had plans to do it." Sizemore insists the love and support of his girlfriend Janelle, who gave birth to the couple's twin boys last month, has helped him turn his life around.

The actor now insists that he's clean after repeated stints in drug rehab centers, and thanked her girlfriend Janelle, who gave birth last month, for all her love and support.

He explains: "All I want to do (now) is maintain my sobriety and my health, so I can take care of these children and give them every opportunity in life... so that they can have a wonderful life."

One of Sizemore's first film roles was in Oliver Stone's "Born on the Fourth of July" in 1989. He has also appeared in films such as "Harley Davidson and the Marlboro Man" (1991), "True Romance" (1993) and "Natural Born Killers" (1994). A succession of well-received supporting parts followed. His first major leading role was in 1997's "The Relic".

Sizemore continued to play leading and character parts in many films, notably "Saving Private Ryan", HBO's "Witness Protection", "Red Planet", "Pearl Harbor", and "Black Hawk Down".
