Giving up the grog for the Hello Sunday Morning programme has been challenge enough in social situations, but what happens if your work demands you drink?
Now that's a problem.
When you're on a set and the director says "drink" , you reply with an enthusiastic "how much? When? Where?"
A while back, a certain beer brand asked me to play a part to launch a "Breakfast Beer" in the US. That's right, I'm in an ad for booze coinciding with the first time in more than 10 years that I've laid off the stuff.
So was I wrong to take a sip of alcohol on set? Yes.
