This is not unlike what every freelancer faces. From my own experience, interleaving work and time off is hard, so don't bet too much on that. It's way more productive to work 4-6 hours in a row instead of eight hours on and off.
Most importantly, do not work on sundays as a norm! It will completely wreck any vestige of being 'off work', and you'll catch yourself on a monday evening wondering how long has passed since last weekend.
YMMV, I'm sure there are plenty other people here who can give you good advice. Good luck and congratulations! :)
Very interesting about working Sundays, I guess the reason why I had included Sunday was because I normally spend at least a few hours coding at the weekend so it wouldn't be a big transition for me.
