Akiko has been keeping a sleep diary for six months. At first she barely managed five hours a night — work emails, a noisy flatmate, a phone that never left her hand. Slowly, things have changed. She's moved her phone to the kitchen, bought blackout curtains and started a strict 11pm bedtime, even on Fridays. "I've never felt sharper at work," she says. "And I haven't caught a single cold in three months." She still struggles with weekends away from home, but she's stopped panicking about the odd bad night.

🎧 Dr. Patel & Sara · GP appointment about insomnia
📄 Show transcript

A: Good morning, Sara. Please take a seat. So, what brings you in today?

B: Hi Dr. Patel. I'm really struggling with my sleep lately. I'm just so tired all the time.

A: I see. How long has Sara been having trouble falling asleep?

B: It's been about a month now, maybe a little more.

A: And when you say 'struggling', how long does it take her to drift off some nights?

B: Oh, it can be awful. Up to two hours some nights.

A: That sounds rough. And what time does she wake up before her alarm?

B: Usually around 5 am, then I just lie there feeling frustrated.

A: Hmm. Has anything significant changed in your life recently? Perhaps around six weeks ago?

B: Well, yes, I started a new, quite intense job six weeks ago. That's probably it.

A: That often has an impact. I see here you downloaded a sleep app a while ago. Has she been using the sleep app she downloaded?

B: Not really — not consistently. I sometimes forget, or I don't feel like it.

A: Okay. So, what does the doctor recommend for the next two weeks? Let's try this: 20 minutes of slow breathing before bed, absolutely no phone or screens for an hour before, then we'll review it. How does that sound?

B: That sounds like a plan, Dr. Patel. I'll give it my best shot.
