Before he sought out an adult sleep coach, Thorsten had spent countless hours trawling online advice about sleep.

“I devoured advice and implemented it all,” he said. “From the moment I got out of bed, virtually everything I did was tailored towards getting a good night’s sleep the following night.”

Thorsten is not an insomniac and his disordered sleep patterns came out of nowhere.

“Every few weeks, I’d have inexplicable periods when I would wake up at 4.30am and couldn’t get back to sleep,” he said. “After a couple of days, I would be making mistakes at work, be bad tempered at home and would start seriously worrying about the impact of sleeplessness on my long-term health.”
