Things that have helped me include:

• an alarm across the room that I have to get up to turn off.
• a light that turns on before that alarm
• an alarm app on my phone that can only be turned off by solving puzzles.
• having an engaging activity that I want to do ready for me and fit into my schedule
• getting up a little earlier so I have time to make a decent breakfast instead of grabbing some trash or just not eating.
• a TV set to turn itself on and set to a channel that shows stuff you can’t easily get used to (the history channel used to show random documentaries in the morning, no idea what it’s like now)
• strict discipline about never sleeping in even when I can.
• avoiding spending time in my bedroom when I’m not trying to sleep.
• setting a reminder to start getting ready for bed
• popping melatonin when that reminder goes off if I’m not already tired.
• drink water before drinking caffeine.
• stop caffeine at least 6 hours before bedtime.
• prescription medication in the morning. Not enough to replace all the other stuff, but definitely something that makes a huge difference with my sleeping disorder.
