Well as a complementary therapist, I prescribe remedies to help with sleep issues so if you can find a herbalist or a homeopath, for example, there may be some help there. A health food shop may also have something to ease the problem. But personally, I find the best remedy is to wear myself out physically during the day, preferably by having fresh air. If I’m indoors all days and not doing much, I sleep poorly but otherwise, I’m ready to drop off ...With Covid, many people aren’t sleeping that well and it’s to be expected, so I would also limit news watching etc., and try to be in a more calm mindset before sleep.
