I get colds once in a while, but other than that I haven't been full-blown sick in years. I haven't thrown up since 7th grade.

However, I do have a flimsy GI tract, and it always ruins my day.

Every full moon I seem to go into seizes and then blackout for a few days, and when I wake up I have terrible diarrhea

Just like I told ya...

I went to a party last night where one of my friends had some kind of headcold, and I wake up this morning with a sore, tickly throat. My immune system is non-existant. I think I need to live in a bubble or something.

I usually don't get sick very often, but I tend to get sick somewhere around the first few months of the year. When I was younger I'd get sore throats, etc around that time, but it's been downgraded to a bad cold as I've gotten older. I guess the trade off is now my allergies are starting to bother me. >.>

I'm pretty much the same way. I'm also sick nearly everyday, and I always manage to get sick at christmas.

I'm the same way. I haven't had mononucleosis because my immune system is topnotch.

I don't know what changed exactly, but I seem to get less colds now than I used to. I was ill once last year when I started Uni and there was the "fresher's flu" going around. It was only a 24 hour thing which wasn't too bad. The year before that though, I got the worse bug that lasted at least 2 weeks.

Ditto here. In most of high school, and little bit before, I used to get really sick somewhere between around October-(early)January. It'd be bad sometimes then too - at one point I had tonsillitis, strep throat and bronchitis all at once. Fucking miserable. Most of my illnesses have been related to tonsillitis though, but I haven't really had a problem with it in the last two years. Once in a while I'll feel kinda crappy or get a fever, but it's not that often.

Not often. An occasional 24-hr-cold. Haven't had the flu or vomited on a long time either.
