I'll tend to manage my time by email a lot, but then if I get beyond inbox zero, I'll process certain things I'm lagging on into my todo list. A lot of my email also files into labels for certain business functions or partners/clients, skipping the inbox, but remaining unread so I can do it in blocks.
But there are cases when you should lose sleep. If your service is down you must sacrifice sleep and keep going until it is fixed. I have done my share of that.
I took the latter path, and now it allows me to keep working on it full-time... but I did have to forcibly sacrifice (I say scupper) some other projects, which I have no doubt would have been equally successful.
