god,i know just how u feel...it happens to me AFTER eating and it happens at home and when im out to eat....i have a massive panic attack which can last hours...it sounds as if your wife does not know about ur fear...u should think about telling her,she would more than likely be very understanding im sure and then u wouldnt be forced to go out to eat as regulary perhaps.I'm here if u want to talk,jade.xx
