I have been on zyprexa for about 2 1/2 years I have tried 3 times to get off it, but each time have had bad anxiety and panic attacks. I am once again trying to get off it, my fourth attempt, I have this time doubled my anti-depressant while trying to cut down on the zyprexa. Hopefully I will succeed this time. I have put on 15kgs. over the 2 1/2 years I have been on it. I also have a headache every day and my eyes are always red and I don't drink.
