I hear ya - and some of that wasn't quite clear from the original post (already doing 70-80 hours, 2 years, etc). And I feel for ya too - I hope it turns around for you.

That said, having net access at home might end up being better, if you can manage it. Depending on the work, it may allow you to be more flexible how and when you address problems, and still have some personal/family time as well.
