Have you ever had these anxiety symptoms, before?

As far, as dealing with a coworker, it just takes time, to be honest.

Do you, see a doctor, for treatment, because nausea and vomiting, do sound like something more is going on, that may need to be addressed.

Sometimes, in a pinch, when I have felt nauseous, I chew some gum. And one time, I had a nurse tell me, that lemonade, helped, and it did.
