How many shots an hour?

I’m gonna drink tomorrow, I have 500ml of 20% spirit and 500ml of 16% sour shot thing. I’ve had alcohol problems before and recently drank very very responsibly, but I don’t get drunk anymore.

How many shots should I have an hour? I weigh 58kg/129lb. I don’t want to black out, but I want to actually get drunk. Also my shot glass is 30ml
