I have been battling to sleep at night which causes tiredness during the day at work. i am a shift worker 6am-2pm ; 2-10 and 10-6 cycle. sinus patient?

Shift worker: and sinus patient, first of, avoid decongestants as Sudafed, or antihistamines wish decongestants, good sleep hygiene: cool quiet bedroom, no tv/smartphone/internet one hour before retiring. Avoid caffeinated beverages few hours before sleep time, have enough rest, may use some sleeping pills or melatonin, if nothing helps see your doctor or find another job, good luck
