Actually the episode lasted about 2 hours. Mindy is N/H. Like I stated I knew she was Hypp, but I lost all rationality because I was working her. She is stalled. I had come early because I had a training session and she was at the corner of her stall. Head down. She whinnied at me, but stayed in that position. Her temp was low at 98.5, she was cold, clammy shocky almost and very listless. I pulled her out of the stall and took her outside. Had her try to eat grass, but she put it in her mouth did not chew it. By this time my trainer was out there and so was my Barn manager. Because of the cold clammy I thought maybe she was going to colic or had perfed her stomach. We did give her the Acetozolemide and Caro syrup and an hour later she had barely changed. The rest was what was posted. In 2 years she has never had an incident with me. It was the gatorade that threw her over the edge. $500.00 lesson, but its only money. The main thing is that she is okay. Thanks for the input. I have read tons on it.
