Manuel P. reviewed Qualia Night
Seems to be effective so far. I tend to stay asleep more during the night and when I do wake up, I easily fall back asleep and feel more rested in the morning
Quali Night
Probably the best sleep hack product in the market. I take it around 7 pm after a meal and by 9 pm, my body gets to a sleep mode as I am an early riser. My REM sleep has increased by about 50%. I take it Sun - Thur and off on weekends and holidays where I can go to sleep late and wake up late.
