Suresh G. reviewed Qualia 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.
Works some of the time for me, non-drowsy.
Day one - worked great. Day two - didn't sleep very well (was preoccupied), Day three - Slept well, Day four - slept well. Day five - didn't sleep well.
