BY The way sorry this isn't directly related to transformers, for the thread leaders.
But for me Themeparkvigilante and my g/f who I go with, we eat before we go on. It's best to do something in your stomach. it's suggested not to go on a coaster on an empty stomach. This allows for your body's signals between perception and actual location while moving pertaining to light and sound to become mixed, thus making you feel sick in a result because your body can't handle the mix up. eating something helps solidify the stability your body has to deal with the perception vs reality thing while riding on anything dealing with motion and g forces. Don't go overboard though, just put something in your stomach. Stay away from as many acid things as possible while visiting theme parks as this doesn't help. Things like oatmeal, water, apple juice, etc.
