"i took this medicine two days ago. the first day i took it around 8pm and couldn&#039;t fall asleep until 3am. i also experienced clenching my teeth that night and it made me so irritable. i noticed my stomach making funny sounds and i took it with a full glass of water and with food  the next morning i woke up with a horrible headache. i had an upset stomach and my jaw was so sore. i felt very nauseated and that passed after about three hours. around 3pm i took it again since i knew it kept me up. i hardly ate at all that day due to feeling so sick. around 7pm i felt like i might be hungry. i went to get fries. when i ate the fries they tasted different.  pristiq made me so sick and made stuff taste different.
