Your body doesn't absorb the drug well without food, which is why they tell you to take it either with a meal or a fatty snack. I just don't like feeling drowsy all evening, which is why I take Geodon with my other bedtime meds and eat something with it.

And I take Celexa too, haven't noticed any problems in combination w/ Geodon or any of the other mess of meds I take for BP, high blood pressure, and diabetes.
