Helps increase total sleep time and sleep quality in people suffering from sleep restriction or altered sleep schedule, e.g. shift-work and jet lag. Helps to relieve the daytime fatigue associated with jet lag. Helps reduce the time it takes to fall asleep in people with delayed sleep phase syndrome. Helps re-set the body's sleep-wake cycle aspect of circadian rhythm.
Just tried this product for the first time. Perhaps it is unreasonable to expect an immediate effect. My problem is the horrible sour/bitter taste of this liquid that claims to be berry flavored.
