Does anyone schedule and "org-clock" interruptions?  I really need to quantify how much of a drain they are to my productivity. I thought I'd include a generic "** TODO Interruption" in my todo.org (or an inter.org file) and schedule it every day.  Then I'd press "I" every time I get interrupted and perhaps tag it with a special term. Or I suppose I could use a capture template just for interruptions. What do you suggest?
