Weird question. How much have you drank without feeling drunk?

I’m currently on my tenth beer in four hours but.. I don’t feel drunk? Usually I’d be smacked about to black out and pass out with this much drink. But I feel fine? Just a bit sleepy. Is this normal? Does anyone else ever get this? I usually only drink about once a week. That one day a week is usually about this amount. And usually over a 6-8 hour period. It just feels weird to me that I barely feel buzzed after what usually knocks me out.
