Honestly until I met my wife, I spent the majority of my time at home building open source projects I knew would save me time later at work, and probably more time overall because the code will be less specialized to the project. This was almost every single night after work.

My wife came along and showed me though that there is more to life than programming and I have to thank her for that. She's a wonderful gruf woman who changed my life. I still code at night on occasion, but not very often. I've got better things to do. I really believe I am happier for it.

All that said, are you entirely sure programming is what you want to do the rest of your life? After a long day of coding I need to be ripped away from its siren song or I'd simply never stop, and I know a lot of developers that feel the same. The job takes a lot from you, imho, and it sounds like you may not enjoy it enough for it to be worth its cost.
