Gender Swaying????

Hi ladies,
title pretty much says it all - anyone done gender swaying? sucessfully?
we have two beautiful girls whom we love very much, and DH has agreed we can TTC for #3! yay!
he did let on he was a little disappointed DD2 was a girl (especially as I was convinced she was a girl during pg), so whilst I would be happy with another girl, I would also like to be able to give DH a son.
I have done a bit of reading, and am concerned about the diet thing - I have to take calium supplements which according to the literature sway pink, but I can't not take them for my own health (though I have considered halving the dosage - atleast till we get our BFP).
would love to hear others experiences - both successful and unsuccessful with their swaying attempts!
thanks!

hi ladies,
