Im feeling dizzy and nauseous. i started feeling like this after coming back from work. i can't sleep cause of the symptoms what could it be. and started vomiting?

See below: First, you should probably make sure that you are not pregnant, or taking any new medications that would cause these symptoms-I do not know what kind of work you do - If the symptoms go away on the weekends, you might be exposed to something at work that is causing the symptoms -see if co-workers are having similar symptoms, and make an appointment with your doctors-good luck

Uncertain: Maybe a viral infection. Rest, hydrate well with water, sip if still nauseated.
