Hi Dom
Print off the information from this site and try and get it to your doctor a couple of days before your appointment. My doctor had never heard of TMAU and it's much easier on that first appointment if you've paved the way a bit.
It took me a long time to make the appointment and it was only through reading what other people have said on this site that gave me the courage to do it.
Go for it!
