Got this product initially for my tired eyes esp my eye bags. Never did I thought it would help on my sleep! I'm suffering from insomnia since 20 years ago, have been to doctors, specialist and even tried sleeping pills. None works. Even with sleeping pills I tend to wake up 5-6 times in the middle of the night. Three times I tried on this product, everytime it helps me to get into sleep without waking up in the middle of the night! I even fall asleep before product was auto shut-off! BEST osim product I've ever gotten!! Thank you!!!
