My wife and I started with the cruise chews after reading the reviews about sleeping better. They worked great! After some months, we switched to space chews and have been very happy. I have an issue sleeping soundly. If you work or have worked in a field that makes it difficult to block out the noise in your mind at night, the space chews have helped me tremendously. I take one chew in the late evening and I sleep soundly all night. If I miss taking one, the restlessness comes back. These chews have been an absolute game changer for us. I hadn’t realized how sleepless my nights had gotten until I found these products. Sign up for the emails, they send online discount codes regularly for big savings. Customer for LIFE.
