Thanks everyone for your steadying thoughts.

I really appreciate it.
Julie, your post totally made sense to me, and I managed to slow myself down and understand what happened yesterday. I think it did all start with the insomnia, and the combination of stressors on top of that sent me looking for some way to keep myself going. So at least I learned something to use in the future, right?
I collapsed last night and slept 12 hours. This morning my stomach hurts and my liver is swollen and tender, my whole torso is bloated and even my hands are puffy. Ugh, ugh, ugh. But instead of feeling angry and upset with myself, I'm just taking notes. This, to me, is really solid proof that my body definitely doesn't like that much wheat. I'm sitting here drinking a pot of tea (very slowly) and seeing how my body takes it. Maybe later, if I'm hungry, I'll have some salad or something else light. I'm definitely listening to my stomach/liver on this one, and trying to help myself feel better.
Hubby is definitely sick, and is on the couch watching old movies right now. I've declared this a day to lay low and take it easy. A load of laundry just finished and needs to be swapped over, but other than that I'm really not making demands on myself.
I hope no one else gets sick.
Carol, I'm trying hard not to jinx you from here!
CandEs, take care of yourself. Lots of vitamin C.

I hope your kids don't catch it, too. Here's to a better day, all.
