So the last time we were at WDW, I got a heat stroke. This led to coming back to the hotel and having the chills non stop for 2 hours and eventually ended in getting the flu...all before the end of my trip...blah! Sooo my question is this; what do you do to make sure stuff like that doesn't happen to you?
Water, water and more water! If I have a fizzy drink, it's usually only when I'm having something to eat (I'm talking meal, not snack!). You really have to up your fluid intake, especially in the hotter months!
I'll do my best to get some healthier foods in each day, usually some fruit at breakfast and I take my multi vitamins with me too, one tablet a day.
Try and get indoors during the middle of the day, 11am - 3pm is usually peak sun shining, so consider going back the hotel, taking a dip in the pool or making an indoor ADR to give yourself a break from the intense heat. (Though if there a 120 minute INDOOR queue, that could help too, though I'm not sure who your sanity would cope lol!)

I totally agree....water all the time. Keep sipping on it through the day. Cooling off in the pool before and after going to the parks is a great help as well. Also when at the parks slip into the shops and take time to ride the indoor attractions. They are air conditioned and give you a much needed break from the heat.
Hydrate Hydrate Hydrate. Take a wash cloth with you to the park and get it wet with cool water to rub on your neck and face to help keep you cool. Remember to keep it in a Ziploc baggie so you don't get everything else in you bag wet. The middle of the day is a great time to take in Hall of Presidents and Carousel of Progress and indoor shows. We also use this time to eat a long indoor lunch. A great way to relax and cool off. Also you know you body and you know your limits listen to what your body is telling you.
I wrote an article about Staying healthy while traveling back in September. Check it out!

Im a personal trainer at a gym, so we have to memorize everything about heat strokes. If you suspect heat related illness you can do a few things: Lie down in a cool place and raise your feet about 12 inches. Apply cool wet cloth to the persons skin. Gatorade, and actually water with salt added are the best, (water works perfectly fine too.) Dont drink too much, about 1/2 a cup every 30 mins. For cramps you can massage the area until it feels better. Heat stroke can send your body into shock so if lips turn blue call 911 because bad heat stroke can cause serious seizures. (happened to someone on my lacrosse team in college)
It is simple to avoid, some of the early signs include Profuse sweating, thirst, fatigue, headache, nausea, and light-headed feeling. So just be aware of your body. Belive me it wont ruin anyone elses time to take a 30 min break from being in the sun. You know your body more than anyone else. I hope this helped, and I hope your next trip is a blast! (with no feeling sick) 
That's Mr. Evil Dr. Porkchop To You!
All that, and wear a hat! Or ears 
Great tips....general consensus says I need to drink more! Has anyone ever tried Airborne?
I haven't tried Airborne but a few family members swear by it.
Handwashing! Now, it won't necessarily help with heatstroke, but it will cut down on the number of germs you're exposed to. If you're on and off attractions (and in queues with handrails) maybe wash your hands every hour or so. I also completely agree with a wide brimmed hat and a cool cloth for your neck. In a bind, you can even get a paper towel from the bathroom, wet it, and cool off your face, neck, arms and legs with it.
Do avoid 11-3 in the sun if you're here in the summer. It really can be very trying, especially with the humidity.

This happened to my husband on one of our first trips! I agree with the water! My husband ALWAYS takes Airborne leading up to the trip and during and swears by it. He actually takes it anytime he feels he is getting sick and he hasn't been REALLY sick in awhile! I would try it!
Also, during mid-day, try and catch some inside shows or rides!
Everyone has good (and similar, which is encouraging that it's effective!) advice. DH got heat stroke on our last trip as well, but he was better in a day. We stayed hydrated but we forgot to put on sunscreen and didn't wear a hat on the first day. Lesson learned!
I got food poisoning. I'd also suggest following the advice printed on the menus that say not to eat undercooked eggs, meat, or seafood.
