I'm Peter. I'm 41, I'm a wealth manager, and I have four kids. I've been married to Amy for 15 years.

I loved her then and I love her now. But about two years ago, the sexual energy just wasn't there. The drive wasn't there.

I knew we needed to do it more, but it felt like a chore.

I was too tired. I avoided the conversation. Part of me worried I wouldn't be able to get it up. It felt like low testosterone.

There was a tension at home. A bit of disappointment in each other for not being better with it. And guilt, on both sides, that we weren't active like we used to be.

I blamed the usual things. My age. Stress. The kids. Hormones dropping, the way they naturally do.

So I tried to fix it. Testosterone boosters. Other herbal remedies. New things in the bedroom.

It all felt forced. An uphill battle.

I finally went to a doctor to look at the drive problem properly. We went through my Whoop data together.

He wasn't looking at my training. He was looking at my nights.

My sleep was fragmented. I struggled to wind down, and I was waking up constantly.

He put it simply. A man's testosterone is topped up overnight. It rises while you sleep and peaks in the morning.

Then he told me the part that stuck. Poor sleep can cut a man's testosterone by 10 to 15%. In a University of Chicago study, that took just one week of short nights in healthy young men.

My nights weren't short. They were broken. He said it comes to the same thing: I wasn't getting the deep sleep my body needed.

My doctor suggested melatonin first. I didn't like it. It left me really groggy in the morning, and it made no difference to my sleep tracker results.

Around then, I kept seeing the same name. The health and fitness creators I follow were talking about 8HOURS. My favourite rugby player, Ben White, uses it and is an ambassador.

Then I saw it in Men's Health and in GQ. That's when I knew it was legit.

So I ordered Sleep & Recovery.

It took around five nights to feel a difference in my sleep.

After about seven days, my sex drive started to come back. It felt like my body had hit reset.

I noticed it in the gym too. I was training much harder, recovering better and building more muscle.

By 30 days, life felt very different.

About a month in, Amy and I had a weekend to ourselves. The kids were at her parents'.

For the first time in two years, it didn't feel like a chore. It felt like us again.

On the Sunday morning Amy looked at me and said, “Right. What are you taking?” She honestly thought I'd been prescribed something.

She was relieved when I told her it was 8HOURS, just a deep sleep aid. I explained what my doctor had told me about deep sleep and testosterone.

She laughed and said, “So all this time, you just needed a decent night's sleep?” We still laugh about it now.

She's loving the new spark and the energy in our relationship.

If you're in a similar position, just give it a go.

There's nothing to lose. They have a 90-day money-back guarantee.

Life's too short not to have a sex drive and enjoy those pleasures.

Peter's story is one we hear a lot from men: years of blaming age and stress, when the cause was the night.

I built Sleep & Recovery because I had the same problem. Stress that never switched off at bedtime, and broken sleep because of it.

No melatonin. No sedatives. Six ingredients, each at the dose the research used, to help your body switch off and reach deep sleep.
