I learned to know about Uppy! from a SAS Captain that uses Uppy! on long haul flights and figured it was worth testing. I used Uppy! on two return trip Copenhagen- Seoul and experienced much less jetlag then normally. The ”hangover feeling” you usually have for a couple of days was not there, just a bit normal tiredness from the time difference. It is an easy to use product, easy to bring in my carry in board luggage and it taste good. If any complaints, I think it dissolved a bit to slow and there was some residual left in the glass even if I stirred.
