Query: Did not work for me

I read all the reviews good and bad and decided to give these a try. I should have saved my money. These did nothing at all for me at all. I tried up to two pills and no difference in my sleep. I must admit I do have sleep apnea and insomnia. But I expected at least something from these but got nothing except a loss of my money. Sorry but that is the way it is.
