Better sleep advice?

Better sleep advice? I have a few conditions that mess with my sleep. I tend to over sleep in my opinion and in my boyfriends opinion (he sometimes calls me so I’m awake at a reasonable time). I can’t even fall asleep without my night meds, if I don’t take them I’m just laying there all night and if I do fall asleep without them it’s only for a small while. I’ve taken them every night for the last two or so months tho. Usually around 10pm when I take my birth control and I’m home from work. I’d say I sleep 10-12 hours a night minus me waking up of course, sometimes more. I have to force myself out of bed, I sometimes just lay there for a while. I have nightmares every night which can lead to me waking up alot during the night (I’d say atleast 3-5 times most nights). I’ve tried easy routines like warm showers and wind down time before bed, taking my meds an hour earlier, melatonin (It doesn’t work without me getting dangerously close to the toxic levels of it). I wanna know if there is anything else out there that have worked for others similar to me or just those who struggle with sleep in anyway.
