CF, the only advice I can give is be consistent with what you do.
What you are going to do will most likely involve tears. Chances are, once your bubs learns what to expect, she will settle almost straight away.
But this may take a couple of days.
Dont waver in your going to bed routine and dont give in and get her up unless you have absolutly no choice. Giving in will only(at best) prolong the angst and (at worst) will cause it to fail.
There is an amazing amount of security in routine and once your bubs knows what the drill is, she will most likely just fit in with it with minimal fuss.
Good luck and I hope whatever you decide to do is successful.
