Chris Evans is the latest star to jump on the celebrity wagon, at least until his 46th birthday this coming April.
The reformed hard-partier, who now fronts BBC Radio Two's breakfast show, told the Daily Mail:
"I've been thinking about it for a good while now. And I simply have to do it.
"I want to know what I'm like completely sober, and to see if I can achieve more without the highs and lows of the gay days and fuggy haze of booze."
