"i have been on pristiq 5 days, the 1st day i felt great, the 2nd, 3rd, 4th &amp; 5th, my last day as of yesterday has been pure hell. nausea, constant headache, flu like symptoms, not being able to read the paper or anything, vision really messed up, hot &amp; then cold, total confusion, can&#039;t remember something that happened an hour ago, my skin itches so bad it&#039;s red. i&#039;m not going to take it ever again, i would rather be depressed, i will take my doctor back the samples he gave me tomorrow &amp; let him know my problems with pristiq. i know an antidepressant can take time to be effective but i don&#039;t want to risk anymore withdrawal symptoms than what i&#039;m having after taking this just 5 days. i will never take it again."
