"i took 3mgs of zyprexa, contained in symbyax, nightly for about 6 years. the medicine worked well for the first 2 to 3 years. around year four i started having severe side effects and did not realize it was from the zyprexa as it had been working so well.  i suffered with increasing seizures for about three more years. bad ones. i wound up in the hospital emergency room and it was the er doctor that informed me that the zyprexa was causing the problem. my regular doctor denied zyprexa as a contributing factor to my seizures. i quit the zyprexa cold turkey. to say the least it was an absolutely horrible experience. wean off this drug over a long period of time and even then get ready for horrendous withdrawal symptoms after your last dose."
