Two Weeks while my kid is with my ex

I find myself in a very different situation for the next couple of weeks.

My ex has my kid.

So, I am taking this time to work on projects and get things done.  On my list is:

Writing,
Watching the last season of falling skies,
Writing,
Working in the garden,
Writing,
Organizing my closet,
Writing,

And oh yeah: Writing!

Seriously, yesterday I wrote somewhere around 3,000 words in the course of 3 or 4 hours.

And I also worked on an article.

Holy word count, Batman!

I am not searching for things to do, I am going to have a pretty busy two weeks. But I wanted to know:

1) If you are in this same type of position, is there something specific you always plan to do when your kid is with the ex?

and

2) Anyone have a reccomendation for a really good mud mask? I figured this is the perfect time.
