Some brands tend to guarantee I get a headache later on, even if I do not over-indulge. Notably the Bud brands and their relatives. For a long time I stopped drinking beer altogether, but over the last few years I have had some intestinal surgery and a hernia surgery as a result of the first surgery. I have found that one beer seems to settle my stomach when I have discomfort in my intestines.
By shear luck, the first beer I tried was a Coors Light, which does not seem to give me a headache, even if I have more than a couple in an evening. I have since tried Michelob Ultra and got a whopper of a headache the next moring. (only two)
What is it in the AB brands that keeps giving me headaches, and what other brands/beers could I try if I am in a restaurant and they do not have Coors products?
