Author David Stewart had it all: the six-figure salary, the German cars, the Swiss watch, and the Italian suits. He had a family he adored in a house by the sea. But he was riddled with anxiety, and he became a dishonest, calculating alcoholic and addict.

In One Day, One Life, he has approached the struggles of addiction and anxiety with candour and balance. This is just the sort of book that can not only change lives, it can save them. His story is told with power, humour, humility, and no shortage of tough love. This is a powerful book.
