Every time you have an experience with medical staff or even worse some of those who work for them. You will have to repeat that. Every function, every hotel, and what is worse is your friends, colleagues and everyone else!!!
Explaining that you are not diabetic, on a strict diet and most places have by now woken up to the fact that there is a lot of people who have an intolerance.
In my old job, I was told by many colleagues to be less free with my rambling on about it! But I was always treated to a ham and mushroom omelette from our chef.
It can be quite comical tho!
If you are ever in a place, always ask whoever is cooking, and get freshly cooked food. In my experience they are usually so helpful.
How are you with fruit?
Keep asking, let us know how you get on.
Best wishes
