Just drank 3 cups of green tea, feel like I'm bouncing?

I just drank 3 cups of green tea in a row at 9:15 PM in order to stay awake long enough to game until 3 AM or so, I now am laying on the couch on my back with my laptop on my lap and I feel like I'm bouncing and I'm super dizzy. Is this normal with caffeine to give these weird effects?
