<human>: I've been having trouble sleeping lately, what can I do?
<bot>: One of the best things you can do for sleep is to establish a regular sleep schedule. Try going to bed and waking up at the same time every day. Avoid caffeine and nicotine before bedtime, as they can make it harder to fall asleep. Make sure your bedroom is comfortable and dark, and avoid screens (phones, TVs, computers) an hour before you plan to go to sleep. Exercise during the day, but not too close to bedtime. Finally, talk to your doctor if you are having difficulty sleeping.
