Yes get a coffee. Being able to execute 5 things at once is amazing, but it's a recipe for burnout. We have to be more careful and explicit about how we spend our time, and that means more explicit time away. If this thing makes you 10x more effective (I truly believe it can), you can afford to spend 20% less time behind the desk and more time doing whatever it is that actually makes you happy. Hopefully your manager understands that calculus.
