Working 1 hour every morning before breakfast worked out well for me. Important things to consider: 1. your life is more important than your side project, so don't prevent yourself from going out at night just to work on your side project, it's ok to skip days. 2. Don't screw around over thinking what you need to implement. Just make a list of small tasks and do them. It's incredible what you can get out of 1 hour with a clear goal and no distraction.

Edit: my work week was 60hr per week. There was no chance I could do anything at night as I was completely drained. Weekends were off bound too. I found that when you do as little as 1 hour a day, if you don't believe in the project you'll just drop it. If you really think you can get something out of it, you'll keep going and you'll get to some place good reasonably fast.
