I eat two potent brownies every day. Doesn't seem to put any strain on my liver, but then again, I'm not on Celexa and Xanax. I'd say make a pan of brownies and eat one the first day, see how it goes. If no probs, eat two the next day, and keep going up until you reach the dosage you want, or you have any probs. I doubt you will experience any probs, but I'm no doctor, so take that with a shakerful of salt.
