Jamie Lee Curtis was "at war" with herself whilst battling her alcohol addiction

Jamie - who is married to 'This Is Spinal Tap' star Christopher Guest - has now been teetotal for 22 years and she couldn't be more proud to be alcohol-free.

Sharing a throwback photo of herself holding a glass of alcohol, she wrote on Instagram: "A LONG time ago… In a galaxy far, far away… I was a young STAR at WAR with herself. I didn't know it then. I chased everything. I kept it hidden. I was a sick as my secrets.

"With God's grace and the support of MANY people who could relate to all the 'feelings' and a couple of sober angels...I've been able to stay sober, one day at a time, for 22 years. I was a high bottom, pun kind of intended, so the rare photo of me proudly drinking in a photo op is very useful to help me remember. To all those struggling and those who are on the path … MY HAND IN YOURS"

Jamie has a family history of addiction as her father, Tony Curtis, struggled with alcohol, cocaine and heroin addiction and her half-brother, Nicholas Curtis, died of a heroin overdose in 1994.

She also battled an opioid addiction after she was prescribed the pain relievers in 1989 after minor plastic surgery "for my hereditary puffy eyes."

The 'Halloween' star spent the next decade stealing painkillers from friends and family until her sister, Kelly, discovered her addiction in 1998.

Jamie later attended her first recovery session in 1999 hoping to break her family's "cycle", which has become her greatest achievement.

She said: "I'm breaking the cycle that has basically destroyed the lives of generations in my family. Getting sober remains my single greatest accomplishment … bigger than my husband, bigger than both of my children and bigger than any work, success, failure. Anything."
