For the first month or so I struggled with the same thing. I have kids too and when I was done with dinner, homework, bathing I was left twiddling my thumbs. TV, books, everything seemed so utterly boring. I would usually go to bed. It gets better with time and you will probably start enjoying the same things you enjoyed before. Or even find some new ones. My attention span wasn't the best early on either so I would read magazines. Do crossword puzzles. Come on SR. Small things that worked my way into bigger things.
