I buy these for my child who has autism and will not go to sleep on his own.. They aren't too strong, and they're easy to chew. They also like the flavor. Within about 20 minutes without any devices or distractions, he's asleep and most nights doesn't wake up again so the sleep is sound.. The amount you get for the price is so worth it. I used to buy it in stores and it was about the same price for half the lozenges. Great deal here and they also work. I wish they did offer more flavors, but the orange is good. Will definitely be purchasing again.
