Is it possible to get nausea just because you had some tea in the middle of a workout?

This might seem silly but this morning I started with a workout routine and mid way drinked some green tea that I made before the workout. A few minutes into the second round of my workout I felt very nauseas and had to stop my workout earlier. Is it due to the tea do you guys think or what? I'm fit so I don't think it's cause of me overworking myself. Keep in mind I also haven't had anything to eat yet this morning as I've tried working out after eating and it didn't work out very well for me either.

Tea had no milk or sugar in it.
