I had a that a few weeks ago, my daughter got it today. I was sooo beat down. Hangover type headache, throat was swollen and it was hard to eat, high fever, whole body hurt, had no energy, nauseated, my equilibrium was off (walked like I was drunk), couldn't sleep at all...did I miss anything...
It took three days with meds to get over the heavy stuff but over a week to get over it all.
I only wish this on one person, one dude from high school I still hold a grudge with from 30 years ago.
