Not exactly sure what you’re asking. But if you’re a night line driver SLEEP DURING THE DAY. Too many guys won’t accept their schedule. “I stay up all day Saturday”. Sleeping in the rest areas Friday (only) nights. I’m a bag of if I’m up between noon & 15:00. I work 18:30-6:30 M-F and do my best to get 7+ EVERY workday. No exceptions in the winter. Just playing with fire.
