Hi Elisi

Thanks so much for your advice.  It's nice to know there are some genuine,
friendly people out there still!  I've taken your advice and now have a
blood test booked for tomorrow for a throid check and to check hormonal
levels, I'll mention the diet if I feel it's relevant at the time I
think.  Once I have the results I'll let you know.

Cheers
