Insomnia has many: Causes: stress, heavy meal before bedtime, anxiety, strenuous exercise before bedtime, too much caffeine/nicotine/other stimulants, swing-shift disorder, noisy environment, bright lights, etc. Addressing these factors may help. Fp can help sort out cause(s) & offer options for treatment.

It can take a while: Retire & rise same time each day. Bedroom should be dark & cool - used only for sex & sleep. Turn off tv. No naps. Exercise regularly but not in late evening. No caffeine for 6 hrs & no alcohol or tobacco w/i 2 hrs of sleep. Dinner should be moderate sized & finished at least 2 to 3 hours before sleep. Can try warm milk, chamomile tea or melatonin along w light reading, warm bath, lavender scent.
