If I were in your shoes I would not even accept a job that requires 20 hours per week to commute to even if it was a great job. Thats a 60 hour work week in my book. If you regularly work 12-14 hours then with commute your job takes away 80-90 hour per week from you.

What you describe is a clean and well lighted highway to burnout even if its a good workplace. And it's not.
