Salt Lick

I stepped out for lunch today, I think I have some sort of low level sickness, maybe for a week - Most tastes are muted.  I just put some salt on my tongue to check, and its taste was muted.  I remember times when I was sick, and I nearly could not taste salt.  But besides taste, the only other symptom I have is a slightly stuffy nose, and with heaters turning on for winter, that seems like a red herring.
