I recently got hired as a train attendant and I know the job requires Attendants to work long hours and with maybe a 4 hour sleep in a 24 hour period. Are there any tips or methods that are used to stay attentive during work hours? Normally when i don't get sleep, my eyes are red from lack of sleep and I need a way to clear my eyes and not make my fatigue noticable. Any opinions or tips from current or past employees is appreciated.
