Very, very busy...
New jobs that are fun and engaging are GREAT, but they are also quite good at keeping you busy enough to not be able to do much else at the end of the day but the basics (food, clean, light social interaction, bed).
It's not so much the job as the training to be honest, I know once I get a basic handle on things and am out on my own instead of traveling long distances to Delaware and New Jersey for class and then shadowing a tech in the field, I'll have more time.
I've been in this kind of situation before and it's a short term thing, but it still forces me to all but drop off the planet in regards to the net regardless of if I wish to or not...
However there is an excellent explanation WHY this is so and someone else already wrote about it... with illustrations!
