i hate to burst your bubble mate
coeliac disease is manageable. it is all about gluten in any form that causes irritation. think of it as an allergic reaction. you consume it - you suffer.
an intolerance is a whole lot more difficult to manage. and something as widely used as wheat really does start to get interesting. its everywhere, and in so many places you don't expect. you might also find that oats and barely could cause problems too.
best thing; get a diary. eliminate everything from your diet week one and go with the basic items that are wheat free. then start to add in other items over time and take note of your physical and mental reactions. find something that disturbs the force then eliminate it. and then continue until you have a full range of products that you can safely consume.
you also need to understand that intolerance reactions in your system drive your toxic levels up. this means you need to think about the level of histamine in your system. the more toxic your system then the more likely you will experience things like water retention, swelling of the extremities, sniffling, mild headaches, low motivation, etc etc etc.
