When you say you are supposed to take .5 xanax 3 time a day as needed, what is the dosage of each pill prior to you halfing it? Did your doctor tell you to increase your Xanax? If not did he approve an increase? If not then you need to call him immediately as I feel from key phrases in your question that you are actually addicted to the Xanax. The most you should take is 6 mg/day, and that is without being on Zoloft. Also, is the Zoloft working for you? What is the dosage of the Zoloft? Why do you need both? You are also increasing your chances of liver damage by taking such high dosage. Keep me posted. Susu
