Yes, it can happen: In large quantities, this can indeed happen. For some sensitive folk, less can do it. For very sensitive (allergic) folk, any can. If this is you, you need to consider reductions in quantity or avoiding it all together. I'd limit my intake to really great coffee in small amounts. It's your choice! good luck.
