"i&#039;ve been on pristiq now for about 4 months. i could tell the difference in my moods almost right away. every little thing used to make me cry, but not any longer. the only side effect i experienced was dry mouth. really wish i  could have felt a decrease in appetite. the withdrawals are pretty bad for me though. one day i forgot to take it and almost pulled my hair out. i was crying uncontrollably over nothing which i didn&#039;t even do before taking the medicines. i was also having major brain zaps. i recommend coming off slowly. all in all though, i love it."
