I've never noticed caffeine affecting my meds. I usually drink an energy drink or coffee in the morning, take my meds in the afternoon with lunch (which sometimes includes a caffeinated tea), have something caffeinated in the afternoon like green tea and then take the rest of my meds right before bed (with milk or water along with food because of Latuda). I self-medicate with extra caffeine on days that I'm depressed. It really helps a LOT with the depression.

Diagnosed Bipolar 2 with OCD. On Lithium, Trileptal, Latuda, Risperdal, and Xanax.
