It's interesting you mention this, I have had a similar experience, exactly with coffee! 😄
Same thing, we tried a different brand of coffee, and I was getting terrible headaches after drinking it. The weird thing as well: the ground coffee had almost a mixed smell of cat urine to it 😵💫 To me, anyway, that's what it smelled like! I honestly wouldn't be surprised if they're actually using it!
But yes, we stopped buying that one. We've never had a bad experience with our regular brand. Glad to hear you were able to pick up the proper stuff 🙏
