User reviews

Sri Lanka to LA with way less jet lag

12.5 hours of time difference usually wrecks me for over a week, so I wasn't expecting much. This helped more than I thought it would. It gives you a simple day by day plan for light, darkness & sleep, and it was easy enough that I actually stuck with it.

The first couple days were still rough, but by day three I felt mostly normal and wasn't fighting to stay awake in meetings, which is a big improvement for me. You do have to follow the light timing for it to work. The reminders help. Wear sunnies when it says no light. Worth it for long distances.
