hey Imigrant. Well, As a kid growing up in a household w/ a cronic clusterhead for a father, and now having about 2 cycles a year myself for the last 7 years, I know a lil bit about ch. Triggers are diff. for everyone, but the most common ones are..Alcohol,chocolate, onions,artificial sweeteners, nitrates(processed foods). Artificial sweeteners giv me a hit like a beer would My old man can just smell onions cooking and get hit. He always kept a journal back in the 80's when he saw that he was all alone w/ this condition. You think doctors are dumb now?? try 1984 Anyhow, hope that helps
