That "stomach drop" sensation on a rollercoaster is caused by negative G-forces making your internal organs float momentarily. To get rid of the lingering queasiness or "butterflies" after a ride, the most effective method is to focus on deep, rhythmic breathing—inhaling through the nose and exhaling slowly through the mouth to calm the vagus nerve. Consuming ginger in the form of candy, tea, or real ginger ale is a scientifically backed way to settle the stomach lining and reduce nausea. It also helps to keep your eyes on a stable point on the horizon rather than looking at the ground or closing your eyes, which can confuse your equilibrium further. If you feel faint, try to find a cool, shaded area and sip water slowly; avoid heavy or greasy meals immediately after the ride. For many, the sensation passes within 15–30 minutes as the body’s vestibular system (balance) and digestive tract return to their normal resting states.
