Can’t get drunk?

I’ve never been drunk, only ever slightly tipsy. Shots do nothing at all. Cocktails sometimes work. I’ve tried every kind of liquor, on empty and full stomachs, mixing, pacing, all of it. Idk if this is relevant but I have ADHD, and energy drinks/coffee do absolutely nothing. My metabolism is super fast too, it’s been all my life. Should I be concerned or is this normal?

It’s kind of frustrating really 😅 I know you don’t need alcohol to have fun but I noticed I’m less shy when I’m tipsy and it helps in social settings.
