You Sleep What You Eat!
Snacks, smoking, big meals and one for the road; enjoyable as these things might be, they can wreck a good night’s sleep.
Watch out for:
Coffee
Teas
Chocolate
Cola drinks
They contain caffeine, which is a stimulant, which can wake you up when you want to sleep. A small amount of caffeine can cause problems falling asleep 10 to 12 hours later.
How to determine caffeine's effect on you? Try eliminating caffeinated food and drink after lunch for a few weeks. Are you sleeping better? If so, guess what …
Alcohol is often thought of as a sedative: a calming drug.
Wrong.
While alcohol may speed the beginning of sleep, it actually increases the number of times you awaken in the later half of the night. Skip the nightcap and see if your sleep improves.
Drinking too much of any beverage can lead to awaking up more, because of the need to urinate during the night. Try to restrict fluids before bedtime to promote a sound night's sleep.
