How to Cure Insomnia and Depression

Dr. William Davis has written a book called Super Gut about how to heal your gut. He says that we can do simple small actionable steps each day and it could cure lifelong insomnia, depression or other health issues. The only thing she can do is eat a small amount of meat each day. And I have a friend that has such bad SIBO that she can she only eats meat. She's basically and she's so, so, so careful, but she can't even use spices. Any, any form of fiber. Her case is extreme, but it was years and years leading up to it.
