I was taking this supplement to help me sleep. They were effective once I started taking two capsules just after supper. However, I did not sleep through the night. I am still trying different supplements
positive

Never received the lights. Email said they were undeliverable? Which is odd because i received other packages from Amazon that day and someone was home all day. Ill look elsewhere.
negative

The dentist suggested I begin using a toothpaste for sensitive teeth since I was experiencing pain while drinking cold liquids. I love this toothpaste, it has helped a ton with my sensitive mouth. The only con is i wish the tubes were larger as I run out quicker than the old toothpaste I was using.
positive
