If it's any consolation, I've had a headache on and off for days and sinus congestion as well. And now that I think of it, perhaps I should be grateful that I don't have full blown allergic reactions going on, as apparently so many others do. I usually get allergies, but I'm trying to be optimistic and hope that the mild headache and congestion is an indication that I'm getting stronger and won't actually get allergies this time!

Think positive thoughts or drink hard liquor! (unless you're "allergic" to alcohol like I am) :-)
