"i started on 100 mg to help with the sexual side effects of celexa.  for the first five months, it worked great (april - september).  at the end of september through to october, i started to have memory and concentration problems.  i started to think i had done things and actually did not.  my last straw was when i &quot;know&quot; i sent an e-mail and eventually found out that i had not.  i &quot;remember&quot; typing and sending the e-mail, but it never happened.  i went to the doctor today and she took me off of it and because of the sexual side effects of celexa, she started me on zoloft.  i have tried paxil in the past, but it gave me hallucinations.  hope the zoloft works."
