I'm pretty sure I'm getting sick too. I've been sniffly the past few days, but when I went to bed last night my throat was getting scratchy. I turned my vaporizer on, which certainly helped me sleep better, but I don't know that it made all that much of a difference in how I feel otherwise. My nose is getting to be very drippy, and that's really quite annoying. Stupid winter. I blame the rapid temperature change from bitter cold to balmy to bitter cold in a span of 3 days.
