@Thusnelda @Xenophon @Dan_Hulson @graf sleep is complicated. so simple sleep aids or muscle relaxants aren't useful. not only are there multiple segments to a circadian rhythm (times before and after dim light melatonin onset) but your hormonal secretions can lag behind your actual rhythm (waking up at a constant time but your bed times change until it syncs) as well as having different lengths of rhythms (normal being 24 hr 5 minutes). melatonin can actually make your sleep worse if taken after dim light melatonin sleep onset, 99.9999% don't know how to dose melatonin properly, etc. effects of things change depending on the relative circadian rhythm, early in the cycle bright light therapy will cause phase delay effects, later in the cycle will cause phase advance effects, etc
