Give the zero-tolerance a go. If it doesn't work, maybe you could try setting aside time to do nothing but daydream - I've always interpreted this sort of thing as the subconscious making demands for time to be creative and make stupid stuff up, so maybe if you sit down and do some journalling, or just sit in a chair and dream away for a half hour or so it might help you focus at other times.
I know that probably sounds like a waste of time, but if it can get everything out and allow you to focus effectively it sounds like a better alternative.
