I'm having trouble sleeping at night. Any advice?

One of the best things you can do to help improve your sleep is to establish a consistent bedtime routine. Try to go to bed and wake up around the same time each day, even on weekends. Make sure your bedroom is cool, dark, and quiet before going to bed. Avoid caffeine and nicotine close to bedtime, as these stimulants can make it harder to fall asleep. Exercise regularly during the day but not too close to bedtime. If you're still having difficulty falling asleep, try some relaxation techniques such as progressive muscle relaxation or guided imagery.
