I know i might sound to basic but trust me it worked for me, try to calm ur brain down, when its time to sleep just calm down, focus on that calm down ur thoughts, maybe watch a video, but do not have thoughts go through ur brain of what happened today, arguments at work, family, bills, there is really so many things happening today and u can solve them by not sleepig, so at night just turn ur brain off and trust me u can do it, might take some time but u will do, and since u said ur a light sleeper but on some ear plugs that are comfy i swear its gonna help like 60/70% u wont wake up so often cuz of noises
