Amy, oh my gosh, I just read this, I am so glad you guys are seeing improvement, that is just great.
I cannot think of a more helpless feeling than when one of my mares had colic, to me it's the worst thing I have had to deal with. I can deal with blood, stitches, etc, but for a horse to be so miserable and there is just nothing you can do but hurry up and wait and hope all the vet has done is going to make everything all better. It's a wonderful thing when they poop, I know first hand.
My thoughts are with you & Esprit!! Take care, and get some rest for you, too.
