I've had a lot more success programming in the morning before going into the office. There might not be as much potential time to work, but I've found myself making more progress getting 30 minutes done a day every day than the intermittent multi-hour blocks I'd program when I had enough energy/motivation after coming home from work.

A nifty trick. It is also not just about the hours you can get out, but also about getting some premium hours with focus and flow. If you do it in the morning you have more of these for your own product instead of for your day job.
