Could you survive an on-air shift without drinking a single cup of coffee? Or even tea?

John Moore does. 

The veteran CFRB morning show host told his audience on Tuesday's show that the only thing he sips on during his four hour shift every day is hot water. 

I guess it's an acquired taste, but I'm sure it soothes his throat. 

I can't say for sure, but I'll venture a guess that he's likely the only Toronto morning radio host to have this on his in-show menu. 

I once did a week of overnights without any coffee just to see if I could do it. I'm not a big java drinker, so it didn't really bother me. But I'm pretty sure for some, it would be unthinkable.
