Taurine affect tolerante of xanax?

Hi, "by accident," I drank a whole Monster energy drink that my roommate left in the fridge, and I'm currently on my Xanax taper. Reading the ingredients, I started researching and found out that taurine can modify GABA processes, so I'm getting anxious (the caffeine in the can already gave me anxiety). I'm worried I'll sabotage this tedious Xanax taper process, which I've been doing successfully for seven months (I still have another six months to go). It's been really tough, and I don't want to ruin it. I'm about to start classes and can't sleep because of a university exam. There wasn't any coffee nearby. What do you think? Did I ruin my tapper process? Because I'm already stable please help.
