I got a cold this week too....luckily it's a small one and just a bit of a nuisance (sp?). Nothing that nyquil at night doesn't fix...don't even need anything during the day.
This is your body's way of telling you that you truly are NOT invincible lol. At least that's what my mom tells me when I get sick....Mom's are always right, ya know!
Keep drinking your fluids, chicken soup, whatever you're doing and you'll be better in no time!
Take care!
