Past experience tells me I'll have adjusted in a few weeks, and filled my time up with enough distractions to rob me of my newfound superpowers, but I'm a little curious as to how sustainiable they might be.

It sounds like it may be valuable to do low-value projects just to stay in the habit of working. Are there any online classes you would be interested in taking, local charities you'd like to volunteer for, or books you'd like to read? (I find reading a book to write a review a good way to give myself time pressure and make sure I'm paying enough attention.)
