Everything You Need To Get The Best Sleep Of Your Life

Imagine going to bed, switching off your light, melting into your comfortable mattress, thinking about the laughs you had with your friend during the day then opening your eyes and realising the birds are tweeting and the sun is up...

You just slept for 8 hours straight and didn't wake once!

Even better, you feel amazing and your sleep tracker shows you got an incredible 3 hours of deep sleep!!

Imagine that for a moment...

How good would you feel?

Now how good would your life be if you slept like this every night?!

This isn't a dream scenario - no, it's a reality! This is what happens every-time I go to bed at night and it's the same for readers of my Sleep Deeper ebook.

Don't believe me, I put my Oura Ring on last night to get some data for this post. Here's my sleep data for the night:

3 hours deep sleep!

And no waking peroids during the night!

I've even had deep sleep scores reaching 40% of my total sleep:


And this is possible through the strategies outlined in my Ultimate Guide To Deeper Sleep ebook!

What People Are Saying:

“I have struggled with sleep for decades. I would wake up feeling tired and just figured that's how everyone feels.

I read many articles on sleep but those didn't really say much except stop drinking coffee and alcohol. It wasn't until I ran across Alex Fergus' work that I realized it can be much different.

My deep sleep went from an average of 15-30 minutes to consistently over 1.30 hours!! Now I wake up feeling refreshed and ready to go on most days!

Thanks Alex!
