Made a little modification on that sentence Forevertoolong. Anyway, My parent's divorced, but I was a teenager (Father was an alcoholic). So being older, not a big deal.
However, I agree with SK, children do adapt, they will probably be about as upset as you show them to be, you know what I mean? Reassurance that Mom and Dad will still both be in their lives etc etc, will go a long way.
It is not pleasant for children to live in a house where there is arguing and drinking (this I know well), it's unsettling and scary. You are actually doing a good thing for them, I hope you know that.
