This product is very, very useful and it works well. The problem I have is value for the money. No matter where this is sold, the price is outlandish. This is an inexpensive mint with a dimple on it. Because they have a patent, they can charge 40 bucks for a bottle which is oppressive for people like me. It is predatory and the sick are stuck. People who use this, can't sleep without it. It should be price regulated or taken by the government for the common good. This is where capitalism needs a conscience but these folks have you by the throat.
