Children are like that. How old must the youngest be now? And the eldest should be in . . . his first or second year of primary school? The memories are a little fuzzy. I do remember I spoke to him once though, and he was four(ish), so he should be six or seven right?
Either way, children are exhausting, but quite fun. As long as they're not pitching a fit. Good God I hate tantrums.
As a non-coffee person, all I can suggest is perhaps decaf? Although the withdrawal could be painful. Or you could switch to good, proper tea.
But definitely relax a little bit. Take a few hours on the swing, have a walk or read a book, maybe play/talk with the boys (it might get them to calm down a little too) and then get back to work.
Is this graduate work now? I remember a while back you were doing some studies too, did you pass that and go on to the next level, or is this the same thing?
But if you do have coffee, have a nice dessert with it. Cheesecake maybe?
Here, have a cyber-lollypop.

EDIT:
Steak or salad?
I'm not a big fan have beef unless it's in a stew, but the salad has to be good as they're so often so bland.
Give me a nice chicken salad over steak any day.
