Allergy, or not?

Lately I have been experiencing stuffy nose and persistent cough, and this happened one night when I slept with the fan right behind me. I am so used to sleeping with a fan turned on, but not on a cold night like that night. I was just too lazy to turn it off and now I am suffering because of my laziness. I think I should be thinking about allergy relief, but for now all I have been doing is drinking lots of hot calamansi juice (aside from the usual bingeing, lol). Sometimes it goes away, and now that it's night-time, it's starting to act up again.

Oh well. I hope that this will be gone when we go back home. Tomorrow. :)
