I stared at the picture of Alex Best, pale and numb, following the news that her husband George was drinking again. It was a look I recognised: I felt sick with pity and full of bad memories. On the morning of our wedding, my fiancé was found by his father, sprawled naked on the floor, after a day of drinking wine, whisky and lager, "to celebrate". Of course, when you're an alcoholic, every day is a celebration.
