Home Economics 101

I've got hit with a nasty cold (again) and I'm curious what other people do to relieve their cold symptoms. What works for you, what doesn't? I've tried to distract myself with things like computer games, my favorite TV shows, and working on a DW style/layout, but sadly, I can't do any of it for too long before I get a headache... I'm also drinking lots of fluids (mostly herbal tee), doing steam inhalation every couple of hours (it's great as long as I keep my head under the towel, but it doesn't seem to have any lasting effect) and I use nasal spray to be able to breath at least once or twice a day...

I hope it's okay to post this here since 'health' is listed as a community interest and I couldn't find another community to ask this question. And I'm desperate ;)

EDIT: Thanks so much everyone, for taking the time and sharing your great tips! I'll answer all your comments in more detail soon (= when I'm up on my feet again) :)
