I have night sweats EVERY NIGHT. It drives me crazy. I've never been on pred and I never had a problems w/ night sweats until I was diagnosed w/ Crohn's three years ago. I sweat so much my hair is drenched, my clothes and underwear are drenched. Last night, in fact, I woke up with a fierce night sweat. I had a sleeveless shirt on and it was drenched like I had jumped in a pool. It's so uncomfortable. I always keep a dry set of clothes handy so I can change without turning the lights on.
