Most of my panic attacks occurred immediately after a meal as well. I discovered a couple of interesting things:

* Magnesium Citrate tablets were able to stop or lessen the attacks, but only when they occurred after a meal. I suspect the laxative effect of magnesium is responsible. * The only food that wouldn't trigger anxiety was coconut-based items, which I suspect has to do with coconut oil comprising mostly MCTs, which take less work to digest.
