My Mother Has Increased Sence Of Smell And Has Vomited

My mother has increased sence of smell and has vomited 15 times already, her body is hot and cold at the same time she says. She ate dinner around 6 hours ago and started feeling symptoms like 2 hours ago. We think it was food poisoning but we wanted to make sure, she is in her early 40s, very healthy and refuses anything but water.
