... it's definitely not *just* anxiety-based, because whaddaya know, I had a completely random attack this morning and sure enough... chills and shaking, although not nearly as bad as it used to be. But what I think used to happen is that it would start as a physiological reaction, but then I'd panic about it (panic attacks were always a huge part of my IBS), and *that's* what would keep me shaking for hours.
