Drank a 5-hour energy 4 hours ago, im nervous, am I on a caffeine overdose?

I drank a 5-hour energy before my hockey game which was about 4 hours ago, now im nervous. Im scared that I might be on a caffeine overdose, am i? I tried drinking water and consuming vitamin C which helped.
im also hypoglycemic but I don't know if im on caffeine overdose o my sugar is just low.

You probably just had too much caffeine. Drink some water.
