I have successful career as a software engineer already so I'll be paying out of pocket. Time wise I've been discussin this with a friend who is in college in his thirties and I will probably follow in his footsteps and stop my personal programming projects while I attend.

Also since my current role at work is in the same vein what I learn will directly and immediately apply to work do that help lessen the impact at work. Even so it will be tough. Very much so you're right.
