[Q]: 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
[A]: positive


[Q]: Order came on time, but the threads on the shower outlet were bad. Had to get a master plumber to fix a less than 10.00 dollar item. A lot of work was done to the bathtub to get to the tub spout. The shower head could not be used nor the tub spout to fill the tub. I expect a full return from Amazon.
[A]: negative


[Q]: In the bottle, several of the capsules had come apart and the content distributed across the remainder. I realized this the hard way. As I placed a capsule in my mouth, and prior to swallowing, I breathed inward. Thus, I sucked cinnamon and cayenne dust into my lungs. I thought I was going to die. Coughing, burning lungs, eyes watering, etc for about a half hour. I have no idea whether the product is otherwise any good, as I tossed the remainder into the trash.
[A]:
negative
