Thank you for your thoughts and sympathy. "Affliction" sounds just about right. I liken this to having one's head pressed up against the big drum in a marching band while the drummer pounds away. OK, maybe a tad overstated — but not in terms of effect on being able to sleep or get used to it. I had jack-hammering going on next door to my house years ago to remove a big river of rock and it was just about as pleasant. And at least it stopped before bedtime.
