Yeah, Still Have a Headache

So I had a headache (though a minor one) for most of yesterday afternoon, despite the supposedly trigger-free lunch. I was able to work out, though, after taking some Alleve. Headache stayed away mostly for the rest of the day and I had a trigger-free dinner. Chicken thighs baked with garlic cloves, fresh tarragon, and canola oil. Accompanied by zucchini sauteed in garlic, canola oil, cilantro and white rice with some kind of oil and cardamom (that could have been a problem- it was leftover from an Indian meal and I'm not sure what all was in there).

Was doing fine today until after lunch. Now I have a bit of a headache. So far today I've eaten an egg cooked with butter, some plain instant oatmeal made with rice milk and topped with raspberries, and some leftovers from dinner last night. Oh, and grapes.

I wonder if the headache I have now is somehow a blood sugar reaction to eating, period? Perhaps it's lack of caffeine? Either way, it's annoying. I suppose it could be psychological. But it's way too early to say that. If this is only day 1 (well, first FULL day on the no-headache diet), I can't really say it's not a food trigger.

Anyway, I imagine eating all this pure food will be good for my weight loss efforts regardless!
