How Can Hypertension Be Treated?

I have hypertension. I take dioxane, norvasc, labateol, chlorthaladon, and clonidine. I am 39 years old. I am 5 2 and weight 164. (My pressure has always been high even when I weighed less). My pressures continue to be very high. Ex: 198/128 yesterday. My insurance won t cover Benicar and I cannot afford it. I have a history of lymes (treated), kidney stones, eclampsia, medullary sponge kidney, nephrocalcinosis. I ve been tested for renal artery stenosis, negative. My doctors have sent me to specialists for elevated liver enzymes and I recently had my gallbladder out, they thought that was the reason. My main concern is my blood pressure. Any thoughts?
