Hi Radioman
I have just noticed your post about Gullon biscuits. I have tried various types in their amazing range, all of them being sugar free, low carb. They are readily available in supermarkets in Spain (where they are made) and Portugal. Unfortunately they are unavailable in UK supermarkets (I emailed their sales department) and also spoke to Asda who do not plan to stock them. If their figures stated on the box are correct they are ideal, and even taste good. Perhaps if enough people are interested the manufacturer may supply. Their range includes digestives, fibre and I think wafer biscuits.
Hope this helps.
