Certainly doable - it is how I did it. Balanced/juggled work, family and school and finished in 3.5 years. Took 2 weeks off to study for the bar and passed - all of the scare tacticts that you need 6 months are bull. It takes a toll on the family - if you have young kids I would not do it, you will miss a significant part of their growth and development. Time is too short for that.
I am a cynical voice when it comes to law school - I do not think it a wise investment for many. Would certainly advise against it if you have a family and kids or are paying full price to go to a T3/4.
