Timeshifter told me to sleep for an hour before arriving in Doha at 4pm UK time, or 6pm local time.
However, I trusted the process, and when it was time to go to sleep at 3pm London time, I actually felt pretty snoozy.
Two hours later (8pm in Doha) I was on another plane (it would be a mammoth 14-hour journey), and it was time to go back to sleep.
While others spent the next few days groaning and popping sleeping pills, I was feeling pretty smug about my Timeshifter experience.
Timeshifter is the brainchild of tech entrepreneurs Mickey Beyer-Clausen and Jacob Ravn, along with Dr Steven W Lockley, an expert in circadian rhythms who supports NASA astronaut training.
