Allergies
"I took one pill at night.  I slept all night and all the next day.   Do not recommend.  I slept all day so don&#039;t even know if it worked for allergies.  Nowhere on the package did I see warning about sleep problem and no additional instructions in the box.  Stuck with expensive product  that I cannot use.  In my mind drowsiness is not the same as being sound asleep for over 24 hours."
