Temperatures need to be a good bit higher. Try for 92-94(preferably 94) on hot side, and 10 degrees cooler on cool side. Low heat equals less than optimal digestion, which is what she's trying to tell you by regurgitating.
I would have a fecal done on her because she has that bloated, yet skeletal, look to her.
She will not poop/has not for a fecal examine.
I am not sure either how to go about getting a very cool side if I turn the heat up, it just gets warm in there anyway, but I will turn it up and see what I can do to get it just right.
