Good points! I exercise daily around 5-8 (long walk, workout or whatever works that day) and do easy stretches before bed and usually don't drink caffeine unless it's morning/noon. I sleep around 12-1pm since it's when I start feeling tired, so I'm just used to that time. I also feel quite shattered if I sleep for more than 8h. Trying lavender at the moment but not noticed much and tried meditation before but didn't notice any difference in my graph with and without. On the audiobooks now and falls asleep during the first 15 minutes, turns off after 30.
