Avoid alcohol, cigarettes, and heavy meals in the evening.
Alcohol, cigarettes and caffeine can disrupt sleep. Eating big or spicy meals can cause discomfort from indigestion that can make it hard to sleep. It is good to finish eating at least 2-3 hours before bedtime.
Wind down. Your body needs time to shift into sleep mode, so spend the last hour before bed doing a calming activity such as reading.
