I am a control room operator and I work alone. I work for twelve hours in rotating shifts. Usually, seven nights in a row with two days off and then seven days in a row with two days off. I normally sleep for seven hours at night. Throughout the day I go through debilitating bouts of sleepiness. This makes me hard to drive and I am unable to work or focus on tasks. Additionally, I am getting frequent hot flashes and dizzy spells. I also feel depressed sometimes. I have no other health issues. I consulted the doctor and he prescribed me Meclizine for dizziness and antibiotics. My BP was 140 by 90 mm Hg.
