Lamb of God’s guitarist Mark Morton has announced he’s been sober for 18 months, sharing the news in a series of tweets.

“As of today, I have been 100% free from all drugs & alcohol for a year & a half… One day at a time,” he wrote. “If you’re reading this & addiction is ruining your life, please know that recovery is possible for you. Find someone in recovery & ask them for help. Life is truly amazing.” He followed the tweet with a list of things he’s grateful for, including his sobriety, the chance to be alive and music — which he adds is “flowing.”

Lamb of God’s self-titled tenth album came out June 19, and they released a series of music videos containing Easter eggs, which lead to a variety of prizes.
