This is how I feel when I'am having low blood sugar. Disney does it to me ever time I go. It is a mixture of excitement, too much walking, and not enough food to fuel your body. All these things that can mess with your regular schedule of meals at home. Some people get really out of whack when there schedules get messed up. And get low blood sugar. It may be too much walking/exercise you aren't use too.
Mild hypoglycemia can make you feel hungry or like you want to vomit. You could also feel jittery or nervous. Your heart may beat fast. You may sweat. Or your skin might turn cold and clammy. You can treat a sudden (acute) episode of hypoglycemia by eating or drinking some form of sugar to return your blood sugar to a normal range. This treatment is usually all that is necessary for an isolated episode of hypoglycemia, such as from prolonged fasting or strenuous exercise without adequate food. Drink fruit juice or sugared (non-diet) soda pop or eat sugar in the form of candy, you should talk with your doctor about what happened. I like to drink the frozen lemonade when I'm in the parks!

For me it is Diabetes. I carry a meter that tests my blood sugar. Twice this last trip I had lows 45 and 65 that is very bad it could cause a diabetic coma. I should have numbers between 100 and 145. I carry glucose tablets that quickly bring my blood sugar up and then I need to eat!!
The trick with Star Tour is NEVER ride in the last top row, WoW that row is a killer!! After I realized different areas rode differently I found the 1st row is best and the sides of row 1 are the least effected. But you have to relax do not stiffen up. Let your back bone slip as the song says. You have to do that on Indy too if you stiffen up you will be sore the next day!!
Bonine and Mechlazine have no side affects. Some people find it has Drowsiness That is why my Dr. said to take it at bed time any drowsiness will have happened while you were asleep. And you will be fine. The Disney Cruises use Mechlazine for sea sickess. Bonine and Mechlazine are 24 hour meds verses Damamine that is every 4 hours!
