Thank you very much for the advice, and for your candour jacqui, Carole, Kat, Mike and the anoynous ones.
Carole, when you say avoiding foods that contain estrogen or estrogenic compounds, what sort of foods do you mean? This sounds promising.
I don't think I can broach it quite the way you suggest, by the way, else she'll be thinking I'm seeing someone behind her back! I may mention Google, however...
