I have has anxiety and panic for twenty years. My daily medicines have worked over the years. I have been on Paxil, klonpin, Buspar, among others through out the years. My body gets used to them so I have to switch. I am going through a divorce, my dog just died last week, family friend past away two weeks ago and recently sold my house. This past week I have been to the er twice. The worst panic I have ever had. I just started taking Xanax today along with my daily meds of Effexor, Paxil and visteril all approved by one doctor and my pharmacy. After taking Xanax tonight I am feeling anxious. Xanax used to help me a lot. I am hoping it will start to work tonight.
