You know the feeling – the knee-buckling wave of tiredness that hits you mid-afternoon. The nodding dog syndrome during dinner. Waking up bright as a meerkat at 3am.

Jet lag is a fickle mistress. Some people are annoyingly unaffected (“Oh, I never get jet lag”); others (like me) can be burdened for weeks. The most frustrating part is the randomness – the will I/won’t I make it to dinner/sleep through the night/be making tea at 4am.

FlyKitt generates a bodyclock-shifting schedule, supported by dietary supplements and blue-light filtering glasses.

A Flykitt costs nearly $150 and claims to prevent jetlag in 93 per cent of cases. Does it work? Is it worth it?

But what if it wasn’t random? What if jet lag was “a choice” and you could “feel great on every trip”? This is the bold claim made by Flykitt, a product that aims to eliminate jet lag and travel fatigue. Developed from research with US Navy SEALs and fighter pilots, it uses an app, a pair of blue light-blocking glasses and a range of supplements to fast-track the realignment of your internal body clock.

Endorsed by everyone from CEOs to sports stars, it reports a 93 per cent success rate and even offers a money-back guarantee. Could this finally be the panacea that frees me from jet lag’s merciless grip?

To put it to the test, I choose the kind of gruelling, multi-stop journey that’s all-too-common for Aussies returning from Europe. First leg: London to Tashkent, Uzbekistan. Second leg: Almaty, Kazakhstan, to Seoul, South Korea. Third leg: Seoul to Sydney.

For this itinerary, Flykitt sends me three kits – two International packs for legs one and three and one Domestic kit for the shorter hop from Almaty to Seoul.

After installing the app, you create a profile (based on age, sex, diet, exercise patterns, caffeine and alcohol intake), then enter your flight details and your desired sleep routine in the destination.

From this, it generates a schedule with the exact times you should wake up, eat, sleep, take a supplement and either seek or avoid sunlight. Each pill contains natural ingredients like B vitamins, magnesium, omega-3s and melatonin to help reduce inflammation, fight fatigue and reset your body clock.

On paper, it sounds great. In practice, it’s less straightforward. For the flight from London to Tashkent, I’m supposed to wear the orange-tinted glasses and avoid bright light for three hours beforehand – not all that practical when you’re farewelling family and negotiating an airport. I’m also instructed to sleep for three hours shortly after take-off – a challenging endeavour during meal service.
