Eat foods high in tryptophan close to bedtime. Tryptophan promotes sleep. Some of these foods are turkey, yogurt, nut butters and figs. Avoid drinks containing alcohol or caffeine as you wind down for the evening. Steer clear of foods containing tyramine close to bedtime.
Tyramine causes release of a chemical that stimulates brain activity.
Some foods to avoid are chocolate, sauerkraut, potatoes and sausage. Induce sleep naturally. Try a warm bath with lavender bath oil or a cup of herb tea such as chamomile. Adjust the temperature of the room - not too warm but not too cool. Ask for a different room if your hotel room is extremely noisy.
