thanks Nicola my symptoms sound a lot like yours I am well skinny but am eating ok, the only worry I have about taking anything is that last year my immune system was only just existent. Do you know if a GP can test your immune system function? I had mine done at a private hospital. My other symptom is Im always freezing. I just dont want to deplete my immune sytem any more because if I have this root canal infection I'll have nothing to fight it off. Gets so confusing . Can docs check for infection/bacteria. Mine are reluctant to do anything but hand out Prozac. Wouldnt it be great if you could stand on a machine like when you weigh yourself and it told you exactly what was going on in your body
