Well, got some blood work back yesterday...lyme titre is high negative, but 
her insulin was way up.  So, we're going to run an ACTH test today.  Have to 
draw the blood and run it to the Tufts Vet School, as it has to be frozen 
within 3 hours and then kept on dry ice, and my vet doesn't have the 
facilities to do that.  DX?  Possible Cushings Syndrome, but who knows at 
this point.  She doesn't really have most of the symptoms for that...no 
coarse hair coat that doesn't shed, nor loss of weight (that's for sure!) and 
this is a disease usually found in much older horses.
So we continue to wait and see...wait and see...This is driving me nuts!
I'll keep you updated.....ever have those days when you just wanted to get 
out of the horse business altogether........
Meg
