I've been trying to go to sleep earlier for a little over a week now (I used to sleep at about 3AM-5AMish and now I'm sleeping at about 9:30PM-10:3PM0ish now). My sleep plan is turn off all the lights, open up my laptop about 30 minutes before I try and sleep and watch an episode or two of futurama on 1.23x speed. I've been getting to sleep every night since on my target time despite being on an Adderall prescription. Futurama really helps for some reason. I'm trying to build it up to the point where I don't need to watch any show to get to sleep early, but I'm not quite at that point yet.
