Cold sweatz

Can anybody help me understand why I keep breaking out in sweat? It's not like I'm getting sick and having cold sweats. It can be wayy before I get sick, or even while I'm still getting high. And for some reason I'll just start pouring in sweat, like ruin a shirt and have sweat dripping off of my face. Does anyone else have this problem or is it something unrelated with my drug use or what??
