Our daughter in law had an episode of heat exhaustion and now has problems every time she gets really hot. She gets confused, lethargic to the point of having to sleep no matter what we do and gets red as a beet. We try to tell her to drink but she is so stubborn, she WILL NOT do what she doesn't want to do. We have finally just gotten to the point that we leave her alone unless she passes out and then we either carry her or call the rangers. She exasperates me to no end!
