Nope! That's the one thing that shocked us. We kept waiting for the "Mac truck" to hit us, the way the flu does, but no go. Instead, we got all of the symptoms, but one at a time. We each had the foggy brain (by far the worst part,) the cough, the ummmm runs ... the killer headache, and any other cold/allergy type symptom, they just rotated through. They never really left, the would just slide to a back burner while another nasty piece took front and center. It was AWFUL! So, at least at our house, it wasn't as intense as the flu, but it was just as uncomfortable and lasted an extra week. No one got the symptoms in the same order or at the same intensity. It was the weirdest bug I've ever experienced ... and I'd just as soon never have to again!
