Oh my, I feel sorry for you for this wasabi experience. It's good that in this dish that I ate you can put on sushi as much wasabi as you want, or even not add it at all ... and as for spicy, Asian food, I remember that I used to go to an Indian restaurant in Copenhagen with an Indian friend and I ate a dish there, after which, just like you in this situation with wasabi, I turned red in the face and I drank 2 glasses of water ;)
