Experiment update

After about 48 hours, I am feeling almost as good as new. However, I am not sure if what I had was a cold--I didn't have the typical cold symptoms and ended up crashing Sunday night, needing to go to bed really early. I probably caught some funky bug after hanging out under the Big Top with all the hundreds of kiddos the day before. Yesterday I woke up feeling about 50% better. Since I don't know what I had, I can't say if the extra VitD helped. I suppose I'll have to wait until I get a real cold so I can try again.
