To answer your question, I was terrified right before it happened the first time, and I tried to fight it for as long as I could. As it was actually happening, I was strangely okay with it, probably because I was shocked that I had actually gotten sick.

In the next episodes, no, I wasn't afraid in the slightest. Episode number two occurred when I was in the shower (my dad said a hot shower might help me feel better). I was washing my hair when I felt it coming on, so I crouched down and barfed. It was just a little bit though. Afterwards, I stood up, said, "Oh, fuck you." (to myself, I was angry that I was having to experience this) and continued to wash my hair.

In case your wondering, I had food poisoning, not noro.
