I'm not entirely sure. Dinner seemed pretty safe (sweet potato) and in the evening I had a soft pretzel (at home, the ingredients were safe). Lunch that day was late, and at a restruant, so that's more likely. I tried to be as safe as a could, had pasta with marinara, bourbon chicken and rice, and a plain baked potato. The pasta might have had oil/ butter, and I don't know about the chicken sauce. So I think that's the most likely trigger (or triggers). I just need to be a bit more proactive at restaurants, I suppose...
