One of the biggest challenges you may face when you discover you have an allergy is to maintain your diet when eating at restaurants.
When I first discovered I was allergic to wheat, I found this difficult and stressful at first.
Over time, you how to deal with restaurants, and and it becomes easy.
The first rule is: don’t be shy! If the restaurant can not cater to your diet, leave! If they do not seem to understand what you want, and just provide placating but unconvincing answers, leave! “Easier said than done” you say? “But my friends, what will they think?” I used to think this way too. One of my big break-troughs was to change the way I thought.
You must convince yourself that the symptoms you will experience from eating wheat are worse than any discomfort you may feel with your friends. They will have to understand that these are your needs, not your preferences. Fix that in your mind, and focus on ensuring that you sit down at a restaurant that understands and can cater to your needs.
