IIf you are reading this, there is a very good chance you have spent the last several months convinced that something is seriously wrong with you.

Not the belly fat. Not the sleep. Something more frightening than either of those. Something that strikes at the core of who you think you are.

Standing in a room with no idea why you walked in. Losing a word mid-sentence that you have used your entire life. Reading the same paragraph four times and retaining nothing. Telling your friend a story you told her last week, with no memory of having told it before. Lying awake at 3am wondering if this is how it starts.

Most women arrive at the same terrifying conclusion. That the decline has begun. That the person they were — sharp, capable, reliable — is disappearing.

It is not dementia. It is oestrogen.

There is a specific, well-documented explanation for exactly what is happening in your brain right now. And a clear, natural protocol for addressing it without waiting for a doctor who will probably tell you it is just anxiety.

This is that guide. I wish I had had it three years ago.
