Works really well for me
I've been using this BioBalance Sleep Cycle Restore more or less continually for the last few months. It very consistently results in my being able to both get to sleep, and stay asleep, more routinely - without any noticeable groginess or 'hungover' feeling the next day.
Sleep cycles can be tricky to manage of course and, in my experience, different things work best for different people. The combination of tart cherry, 5-HTP and magnesium in this product certainly seems to work well for me personally.
