Love @louistheroux documentaries... #DrinkingToOblivion was a really interesting insight into alcoholism. Wishing #joewalker the very best — Susan. (@susanwxox) April 25, 2016

One participant in the documentary really pulled on views heartstrings. Joe Walker, 32, moved viewers to tears as he was shown walking out of hospital trying to buy vodka. The university medical researcher, who had previously been sober for a number of years, had relapsed resulting in the demise of his relationship and the termination of his employment. Through tears on the programme he told Louis: “I don't want to be a drunk - I am dying as a person.” Now Louis has caught up with him and reveals that Joe is 8 months sober and has resumed work. Joe looks happier and healthier and we wish him continued success with his recovery.
