I started my family on the diet three months ago – successfully - for my son. After a weekend away, just me and my hubby, eating all the things we haven’t eaten for some time, most of all flavoured chips, I got mouth ulcers back again. This is something I have suffered with for many years, I have often feared it to be cancer, and had swabs taken etc to no avail. I hadn’t really noticed that they had gone away, till they came back again within 2 days - unbelievable! – Rachael, by email
