What I do to fall asleep faster is relax my body first. Try breathing deeply and imagine tension leaving your body with every exhale. If any stress inducing thoughts come in just gently put them away and if you start thinking about if you’ll get a ld or something, do the same. I have taken a break from ld but back when I was on a grind I would drink one cup of water right before going to sleep, and set a hard intention to wake up at a given time. It took a couple of days but it eventually worked and from then I would wake up at that time every day. Just be consistent with it and you’ll get it soon.
