Sleeping Tablets or CBT for Insomnia? What to Try First

If you've been lying awake wondering whether to ask your GP for sleeping tablets or to try cognitive behavioural therapy for insomnia, you're not alone. Both can help, but they work in different ways and suit different situations. This piece sets out what each actually involves, so you can decide what to try first.

---

In short: Sleeping tablets can help briefly but tend to stop working and mask the real problem, while CBT for insomnia treats the underlying habits and thoughts that keep you awake, making it the better long-term option for most people.

• Sleeping tablets often lose effectiveness within weeks and can cause rebound insomnia when stopped
• CBT-I is a structured programme covering sleep restriction, stimulus control, cognitive work and a sleep diary
• Short courses of medication are reasonable during acute crises or as a bridge to starting therapy

Why sleeping tablets stop working

Sleeping tablets, such as z-drugs or benzodiazepines, work by sedating the brain. They can help for a few nights when you're in a crisis or your sleep has been disrupted by a specific event, a bereavement, a big deadline, a sudden shock.

The trouble is, your body adapts quickly. After a week or two, many people need a higher dose to get the same effect, and the tablets stop working as well as they did at first. When you stop taking them, sleep often gets worse before it gets better, a pattern known as rebound insomnia. That can make it feel like you need the tablets again, even though your original sleep problem was never actually treated.

The NHS advises that sleeping tablets are usually only prescribed for a short time, because of the risk of dependence and because they don't address what's keeping you awake in the first place. This doesn't mean tablets are dangerous when used carefully and briefly, only that they were never designed to be a long-term solution. The underlying causes, worry about not sleeping, irregular bedtimes, too much time spent awake in bed, racing thoughts at night, stay exactly where they were. The tablets mask the problem rather than resolve it.

What CBT for insomnia actually involves

Cognitive behavioural therapy for insomnia, usually shortened to CBT-I, is a structured programme rather than a general conversation about stress. It's recommended by the National Institute for Health and Care Excellence as a first-line approach for long-term insomnia, because it treats the causes rather than the symptoms. A typical course covers:

• Sleep restriction: reducing the time you spend in bed so it matches, more closely, the time you actually sleep. This sounds counterintuitive, but it rebuilds the natural pressure to sleep.
• Stimulus control: using your bed only for sleep, so your brain stops linking it with lying awake, scrolling or worrying.
• Cognitive work: identifying and challenging the thoughts that keep you alert at night, such as catastrophising about how the next day will go.
• A sleep diary: tracking your patterns for a week or two, so any changes are based on your actual sleep, not guesswork.
• Wind-down routines: tailored to what genuinely settles your nervous system, rather than a generic checklist.

CBT-I takes more effort than swallowing a tablet, and the first week or so can feel harder as your sleep schedule tightens. But the improvements tend to last, because you've changed the habits and thoughts that were keeping insomnia going, not just covered them up.

When short term medication is reasonable

None of this means medication is always the wrong choice. There are situations where a short course of sleeping tablets makes sense:

• You're dealing with an acute crisis, bereavement, sudden shock, or severe short-term stress, and you need to function over the next few days.
• You're waiting to start CBT-I and need a bridge through the worst nights, under your GP's guidance.
• You have a specific, time-limited reason for disrupted sleep, such as shift changes or acute pain, where the sleeplessness isn't yet an entrenched pattern.

In each of these cases, the tablets are doing a specific, limited job: getting you through a rough patch, not fixing insomnia as a long-term pattern. The key word is short term. If you've been taking sleeping tablets for weeks or months, or you're increasing the dose to get the same effect, that's a sign to speak to your GP about what's actually keeping you awake, and to think about CBT as the next step rather than more medication.

A two week plan to start this week

You don't need a diagnosis or a referral to start improving your sleep. Over the next fortnight, try this:

Week one:

• Keep a simple sleep diary, noting when you go to bed, roughly when you fall asleep, and when you wake.
• Fix your wake-up time, even on weekends. This tends to matter more than fixing your bedtime.
• Cut caffeine after midday and reduce screen time in the hour before bed.
• Get some daylight exposure earlier in the day, and keep physical activity away from the last couple of hours before bed.
• If you're lying awake for more than twenty minutes or so, get up and do something calm, then return to bed when you feel sleepy.

Week two:

• Review your diary. If you're spending long stretches in bed awake, try going to bed slightly later, so your time in bed matches your actual sleep more closely.
• Build a short, consistent wind-down routine, the same few steps each night, so your brain learns the cue.
• Write down the thoughts that come up at night rather than trying to solve them at three in the morning.
• Notice whether your sleep is improving. If it isn't, that's useful information, not a failure.

What to do this week

Start with the sleep diary and the fixed wake-up time today, if you can. Those two steps alone often make a noticeable difference within a week, and they'll also give your GP something concrete to work with if you do end up discussing medication or a referral.

If your sleep problem has lasted more than a few weeks, it's worth treating it as something to actively work on rather than wait out. You can raise CBT-I with your GP, look into NHS talking therapies, or start CBT for insomnia with a private therapist, including through services such as Mind a Porter, if you'd rather not wait for a referral.

Whichever route you choose, the underlying point stays the same: sleeping tablets can get you through a crisis, but CBT for insomnia is what tends to actually fix it.

Frequently asked questions

Why do sleeping pills stop working? Your body adapts quickly to sedating medication, often requiring higher doses after a week or two to achieve the same result. When you stop taking them, you may experience rebound insomnia where sleep gets worse. These tablets mask your underlying problems rather than addressing the habits that keep you awake at night.

What happens during a CBT session for sleep? CBT for insomnia is a structured programme that teaches you practical techniques to manage your sleep patterns. You will focus on identifying unhelpful thoughts, using your bed only for sleeping, and adjusting your time in bed to rebuild your natural sleep drive. It also includes tracking your progress through a personal sleep diary.

Can I use tablets for temporary sleep issues? Short courses of medication can be reasonable if you are facing an acute crisis, a bereavement, or a sudden shock. They help you function over a few difficult days while you navigate a specific, time-limited event. However, they are intended as a temporary bridge rather than a long-term solution for ongoing sleep problems.

How can I track my own sleep improvements? You can start by keeping a simple sleep diary to note when you go to bed and when you actually fall asleep. Reviewing this information over two weeks helps you see your patterns clearly. If you spend long stretches in bed awake, you can adjust your bedtime to match your actual sleep time.
