Works like a dream as advertised and this seller has the best price!
I made me sleep within an hour or more but I slept through the night and was still able to wake up to empty my bladder and go back to sleep.  The first use left me feeling a little groggy for over an hour.  However, the more time has passed I am feeling very good and refreshed in the morning.  This is great stuff!
