I don't do this. I don't get the "24-hour bug". I've never quite understood it when people expect me to be All Better the next day -- for me, a "cold" sticks around for a week, on the rare occasions when it doesn't give way to something more severe.
This is the second time in the last six months that I've had a "24-hour bug" (really more like 48, if you count the first onset of "is that really a symptom?"). I've had nothing more severe than that in that time -- knock on wood.
I'm running through the variables, and I'm startled to realize that it may be associated with my change in eating habits back in May.
Good golly, eating better just might make you healthier, in a tangible, noticable, everyday sense.
