Fuel up properly

A lack of vitamin D or magnesium tend to make you feel more anxious.

Eating vitamin D and magnesium-rich foods a few days in advance can be helpful to buffer the stress.

Grab some fortified milk, yogurt, and Brazil nuts before an event. They contain selenium which helps manage anxiety, depression, and tiredness.

Ensure to eat before networking to prevent showing up with a growling stomach. Also avoid sampling cuisine you've never had before, incase it doesn't agree with you.
