Poppy, I feel your pain. I thought I was the only one going through this. Its been almost 2 months since I have been on the Geodon. Its been almost that time since I have gotten much sleep. I can't function! I take it twice a day. I am tired all day. I pass out on the train. The sad thing is that even if I try to go to sleep, I don't really sleep--it's just bad insomnia (even at night), the worst I have ever experienced in my life. I am normally a great sleeper.
How many milligrams are you taking? I am taking 60 mgs twice a day.
I have also been taking Melatonin, an over the counter sleep aid. It only helped somewhat, but I spent half the day today with the same insomnia.
I talked to my psychiatrist about this. I saw him twice this week over this Geodon issue. (Plus its got major drug interactions with antidepressants, which is supposed to be "rare.") He prescribed Trazadone, an antidepressant sleep med. According to him, it is not habit forming and it is for major depression, which I have. I am hesitant about the drug interaction with the effexor, which he prescribed with the Trazadone, because it can cause serotonin syndrome, which can be fatal. All these drug interactions scare me. Plus, I did not want to take the Effexor with the Geodon because of QT levels with the heart. According to my psych, it is only congenital meaning from birth, which I don't have. Yes, I share your frustration level.
My system is out of whack as well, because I stopped taking the Effexor for a day, which has withdrawal symptoms and I am introducing new medications as well. I was doing really well on the Zyprexa, the major drawback was weight gain--and I was not getting much exercise--so my psych wanted to stick me with the Geodon for that reason. Like you said the Geodon has been helpful, except for this major side effect.
