Ahh, decisions, decisions...
It's hard to give it all up, the extra money, the career, the secure position you might not be able to get back...
I'd vote for a few months off. You tend to forget the "good life" when at work every day, and a few months off would revive that memory and vision of a new life. You'll see if you still like it. The thing is, as you have discovered, that corporate life does tend to get better with age, with more respect, power, money, etc. so it might be worth it to stick it out a little longer!
The real question to answer during your sabbatical is: do you prefer the "good life" or power/money/recognition a career can provide?
