Jason Isaacs thought he was 'going to die of drugs' before getting sober.

The Harry Potter actor marked 28 years of sobriety by delivering a poignant video message to his Instagram followers on Tuesday. "28 years ago today I woke up having spent the night without drugs, that was the first time that had happened for decades. Drugs or drink, and I've lived a life that's drug- and drink-free since.” Jason insisted that he wasn't telling his story to "celebrate" himself but to give an example to others who may have the same struggles and think there's no way out.
