Hi there.
Sleeping pills can be affective, one common side-affects are; "slower breathing" -- slower breathing is a common factor, as a side affect. Another would be "depressed breathing".
These happen for many reasons, forcing your body to sleep isn't on the "healthy" side of your body.
Sometimes, people do get addicted to sleeping pills; and take them every night and can lead to small or major health issues.
An unwanted pill that goes into your body every night will cause unwanted side affects. That can be very harmful!
Skin cells are made of proteins, water, and fat. But brain cells are only made up of amino acids, which ca make protein.<span />

There are 4 outer atoms and lone pairs that are present in a molecule with a see-saw shape. It was called "seesaw" comes from the observation that it looks like a playground seesaw. It is very common that four bonds to a central atom result in tetrahedral or, less commonly, square planar geometry.
