Years ago, I worked with someone who employed sugar all the time for that purpose. Can't say I've heard anyone use it lately in this neck of the woods, but it did used to be fairly common.
Nowadays, I think, profanity has become so much in common useage that most people of my generation would probably just say s*** and not think twice about it. It's become a fairly mild expletive, although not as mild as damn or bugger.
