Treehugger, I've not read the entire thread, but I just wanted to give some advice based on my experiences over the past 3.5 years of constant study (first, an intense local theological program pretty much on par with grad school, and then the past 8 months studying for the customs brokers exam). I don't remember what your family situation is like, but you may find that studying a certain way works better than what you thought. I've been getting up very early to get an hour of studying in before going to work, rather than after work, since my brain is fried after some seriously long days. As much as I hate mornings, it works!
