"i took the 50 mg dose and within the first couple hours felt sick to my stomach.  during the night i felt like i was half asleep but never fully out.  i had a hard time getting up the next day.  i felt light headed and kept yawning constantly.  i felt like i was in a fog that didn&#039;t break until about noon.  later in the day i had a headache.  i wouldn&#039;t recommend this particular drug."
