I work nights as well, I get my sweat at night. Regardless if i sleep or not. But when i sleep at night I wake up like if 7 guys pissed my bed while i was sleeping, i mean it smells like piss and im drenched. At work, its not that bad. However I sweat more all the time, constantly with drops on my forehead, people ask me whats up all the time, I just say its fucking hot in here.. lol.
