Oddly this website is often referred to by reputable news outlets like Dr. Oz. It offers a cognitive behaviour therapy program for sleep problems. For a fee you get a 5 week program supposedly monitored by a Dr. Gregg Jacobs. Two problems:
1. The provided material is nothing new and can be found all over the internet.
2. Contact by email with the site will get you a rude, bizarre diatribe no matter what question you ask (Don't expect a useful answer) and threats to block you from further support.
Don't waste your money. You won't get any value and the email abuse doesn't help. Honestly a strange way to do business.
