Thanks again for the words of encouragement.
I am hoping it will be mild. Fingers crossed.
Hopefully having all those boosters will help.

Just one data point, I know. I got it a few years ago now; my case was relatively mild (mainly chills and loss of appetite), and my SO caught it from me. His was much worse—he had only the one vaccination and no boosters—while mine was much less: I get the boosters as they are available.
