First let me say that the customer service is awesome! My order was delivered an hour after I ordered and Nick included two face masks (I am local). As for the product itself, wow! My son is on the autism spectrum, he has a lot of anxiety and gets stressed very easily. This product has been a game changer for him. He's been taking it for about three weeks now, but we saw the difference in about three days. He used to get anxious over the everyday things and tiniest inconveniences, but now he just takes everything in stride. I also use it for anxiety and insomnia and all I can say is that it works and it works fast.
