I get headaches when I drink Gin, but not vodka

I can drink almost anything, be it from beer, to red wine, to whiskey, no problem. But for some reason, I have the smallest amount of Gin and I get an insta headache. I’ve noticed it with certain gins, not all. Tanqueary, for example, but not Hendricks. Hell I can even drink Kirkland (Costco generic) brand sometimes. But others will give me the mother of all headaches. Anyone else have this issue? Sorry if this has been mentioned elsewhere, I googled this and found very little help on the specific subject of Certain Gins.
