Managing Anxiety. It is understandable that anyone feels anxious or nervous if they are worried about vomiting in public. Few things would be more embarrassing than regurgitating in the presence of someone special while on a date or in a business meeting. Getting sick in class is also not ideal. This type of worry is the very cause of many people’s inability to control nausea. It is true that worrying about throwing up can actually cause you to finally vomit in front of others. Instead, refocusing your thoughts on something more soothing can help you manage your anxiety. That idea of your troubles being all in your head is very true as it relates to anxious feelings. Concentrating on slow and even breathing can help prevent this type of negative feeling. Drink some cool water and think about each breath as it flows from your body as a good way to prevent this worst-case scenario.
