i don't drink energy drinks but i do drink tons of coffee. I take lithium and the coffee like any caffeine causes my lithium levels to drop. When I was drinking even more coffee than i do now, I definitely noticed a differance in my mood. it was more volatile. I assume the energy drinks could do the same. As far as alchohol, I don't drink at all. In spite of zyprexa weight gain, I'm still a fairly small person and i can not handle alcohol mixed with my meds. It makes me sick and messes with my mood. That doesn't seem to be the case with you though. I would just say use moderation.
