What if i feel like i'm going to pass out sweating and almost throwing up?

Sit/lie down: These are the symptoms of acute illness. You probably have a viral infection/syndrome. Antibiotics won't help. Often you don't feel like drinking, but you need to if you are sweating a lot. This leads to dehydration. Rest, drink fluids especially containing electrolytes such as Gatorade, eat a BRAT (bananas, rice, applesauce, toast) diet. If not better in a day or two, contact your doctor.
