I've been having trouble sleeping lately. What can I do to get better sleep?

One way to improve your sleep is to establish a consistent bedtime and wake-up time. Try going to bed and waking up at the same times every day, even on weekends. Make sure that your bedroom is cool, dark, and quiet. Avoid caffeine, nicotine, and alcohol before bed. Exercise during the day but not too close to bedtime. If you're still having difficulty sleeping, talk to your doctor about possible underlying medical conditions or medications that may be causing the problem.
