In 94 I had the Asian flu/Bejing flu, which IIRC is another H1N1 variant.
I was IN BED FOR EIGHT DAYS STRAIGHT!
This time is was only four and a half or so.
I would rate that one a nine, this one about a 6
I think when I had that Asian flu, that was the sickest I have ever been in my life (I’m in my 50s)
