Make sure your mobile is turned off and at least 3 meters from your head when you sleep;

Remember at least 15 minutes of Sun a day [not midday Sun which may burn];

and not medical advice,
i take 5mg+ of melatonin with 500 mg of Niacin [not no flush, which is not bio-available, if you get flush, then take the melatonin 15 minutes before the niacin, if you still have flush add melatonin], and add 500mg+ of arginine to get a great nights sleep..
