After many years of sleep deprivation, both in falling asleep and getting back to sleep if I wake, these patches are working so well!! I've tried magnesium sprays, compounded melatonin capsules, chamomile tea, yoga, lavender etc with no success, but these patches work for me, and so quickly! I feel drowsy and relaxed within half hour of applying, and definitely feel my sleep is deeper and better quality. Though I still wake during the night, it is much easier to nod back off, thank you!!!
