Tequila does nothing for me

I’m just wondering if anyone else has noticed anything like this. I(48f) have drank alcohol on and off through my life. In my early 20s I drank more than any other time. Pretty much quit for 15 to 20 years while I was raising my kids. Now that they’re all in their 20s I started drinking socially again. I say all this to say it’s in no way that I’ve become desensitized to tequila. I’m more of a champagne drinker when I do drink. I was recently gifted a 750ml bottle of patron. I drank half the bottle in a matter of 4 hours and almost got tipsy(my husband had whiskey so it was just me drinking the tequila). I had a few shots and made like 3 ranch waters. Wth. Is it just me?
