Day 12...thinking about breaking...

I have felt great up until today. I woke myself up this morning while trying to munch down on dream carrot sticks :)

But...that was fine...today, I have been irrational and emotional and very very anxious. My chest hurts, and for the first time I'm getting head rushes when I stand up. I only have two more days to go, but it seems like my body is signaling that it's time to break.

Any feedback? I am sure I can stick it out if that's what I choose, but I want to respect my body, too.
