Twice. First time was 24 hours of the absolute worst I have ever felt, but bounced back quickly. By Day 2 it was like a cold. I would still say I've had worse flus, simply because I had no stomach issues, so I didn't have to get out of bed. Second time I only tested because I was going to meet my newborn nephews, but I suspected it was allergies. It was not. It felt about like I feel after doing a full day of yard work in May.
My wife was the opposite. Her first was pretty early, but was extremely mild. Her second time was way worse. She's a teacher, and we have 3 kids in 3 different schools (all different from where she teaches) so I assumed it has been brought into our house other times, but only one son has ever tested positive, and just once.
