Should I stay or should I go?

Seriously thinking of quitting my job and having a month off before looking for something new.

The new line manager has just sent me an Email saying:

"Hello J,
I am very keen for you on a monthly basis to spend time on-site here at Norwich. What I am suggesting that you spend a week a month on-site, does this work for you?"

I was thinking of replying along the lines of

"Dear line manager / corporate goon, I have 2 kids under 7 and my wife works full time as well, what do you think?"

So I am seriously weighing up my options, it's not as if the job pays well enough or is exciting enough / look good on my CV enough for it to be worth me missing out on my family for 1 week in 4. Having typed this I have just realised I am turning down staying at a hotel with a free meal and no kids screaming at me for 1 week every month, am I insane? ;-) 

I have some money saved so I will be able to cope for a few months without pay and I will be able to in inverted quotes "concentrate on my health" (whatever that means, probably sat on my arse watching films I taped from film four, sound good to me ;-)) But seriously, there's all this stuff with Kalydeco kicking off, I have lost 20% of my lung power in the last 4 years, so it may be interesting to see if I can reverse it / get to the bottom of it with my team, who knows? Need to decide by Friday though...

It is Oscars birthday tomorrow, he is 4. He is still obsessed with Pirates, is reception ready for him? And will he learn not to wet his pants on a regular basis before he starts next month?
