I believe I have food poisoning, what should I do for the vomiting?

To treat nausea and vomiting due to food poisoning, you can try taking Gravol, which is available over-the-counter at the pharmacy. It comes in various forms, including suppositories if you can't keep anything down. If you're unable to go get it yourself, consider calling the pharmacy to see if they can deliver it to you. Drink fluids slowly and stick to light liquids like soups, broths, and water. Avoid sugary drinks like Powerade and most Gatorade, opting for the G2 range instead. If you're unable to drink anything for an extended period, it's best to seek help at the emergency room.
