I think taking it at lunch is perfectly fine. The problem is that Geodon has a short half life, like 5 or 8 hours. My old pdoc told me to take it all at night (80mgs) and everything was fine. My new pdoc is better, and she would have me take 40mgs also in the morning to keep it more steadily in I the blood stream. I use to notice withdrawal form Geodon towards the end of the day when I would just take it at night. The only symptom of withdrawal was kinda like a brain zap, but it was so weak and infrequent it didn't bother me at all. Make sure you eat a hearty meal with it!!!
