"i took this medicine for the first time last night and i will never take it again. my doctor told me to take a half of the 100mg before bed. it knocked me out for 14 hours, i woke up and felt in a daze, i was unsteady on my feet, i had the worst migraine of my life to the point where i couldn&#039;t get out of bed. i felt terribly nauseous. i ended up calling out of work."
