Am I an alcoholic or does Fireball feel and taste more like 20%?

I would drink a bit over half a bottle (like 400mL) of the 33% Fireball and two coolers in a night and be 5/10 drunk. But I have been drinking that consistently for a little while.

Then I got 40% Gordon’s gin. Gin fucks me up and it hits fast. I had maybe 90mL and one cooler and I got 9/10 drunk.

Anyone else notice the same thing with Fireball?
