It might feel like a big step at first, but there is no reason why you shouldn’t be able to enjoy a meal out in a restaurant.
Be well-prepared
You can always contact the restaurant before you go so that you are prepared ahead of time, and a lot of the bigger restaurants have their menus online so you can always check the menu before you arrive at the restaurant.
Where to go?
A good idea is to start with a restaurant you know well and keep it simple when ordering. There is no need to be too cautious, just be practical. Order what you want, but be aware of how certain foods make you react. Also, don’t be afraid to ask the waiter what ingredients are used for the meals.
If possible, you may want to order a type of food that you have already tried at home first so you know how you will be likely to react. As you slowly eat more and different foods, you will feel more confident when eating out as well. Even if you are used to having a drink at home, it could be best to 'start small'. For example, drink a small beer rather than a large one. This will help your body build up your tolerance to alcohol again and help reduce – or completely avoid – any reactions.
