What in the world?

I'm seriously confused right now by what is going on with my body.  More specifically, it's my stomach or some part of my digestive system that seems to be going completely insane since Sunday.
Early Sunday I woke up with the headache of all headaches at like 4 am.  I staggered to the kitchen and in the dark couldn't find a regular pain reliever.  But I'd been having some sinusey stuff so I just grabbed the Tyelenol sinus.  Then I laid down and about a half hour later I was hit with this horrible stomach pain.  I was mildly nauseous but never got sick but my stomach was in this horrible not.  It was like an evil cross between the pain you can get when you're really dehydrated and when you're really really hungry.  I wondered if I would make it through our busy day.  I ate some breakfast and felt hugely better.  But by the time we ate again I was miserable.

And it's continued like this all week.  I feel like I"m starving to death.  I KNOW I'm not dehydrated because I've been drinking 100+ ounces of water a day.  But this can NOT be the new normal.

My husband just pointed out that my removing sweets (ok I have a tiny bit here and there now since Lent is over but NOTHING compared to what I used to) and soda has made a noticeable improvement.  I can't start eating like some high school football player now!!
