long hours - really worth the overtime pay?

I've worked 10 hours days the past 2 days. So, add in the commute and my lunch break and I'm away from home almost 12 hours. Talk about exhausting.

I'm wondering if it is really worth it in the end for the overtime pay? Besides the overtime pay, I get the perk of missing rush hour traffic as I've been arriving early and staying late. It's always very quiet when I get to work and at the end of the day as no one else is as crazy as me and working these hours. The downside? I spend most of my waking hours at work, or driving to and from it. By the time I get home I don't want to spend time cooking, so I end up eating something quick, which usually means not as healthy. I don't feel like working out as it is 7pm when I get home and I need to eat dinner, do the dishes and so on. Ah, I just don't know.

It might be easier if my employer isn't an internet Nazi - then I could pay my bills, etc. online at work when I got a chance. Instead, I have to add that to the after 7pm task list.
