(I don't remember where I got this picture, oops)
Last night I got in bed and noticed that the air-conditioning duct above my bed was condensating. That's right. Dripping onto my bed, my carpet, everything. Appropriate measures have been taken, but I really need a dehumidifier, stat.
Update: windows closed (check). fans running (check). dehumidifier bought off craigslist (check.) room dry and smelling normal (check).
