Trying To Control BP. Severe Anxiety, Chills, Unable To Sleep. On Clonidine, Lotensen, Benicar. Suggested Edarbi, Norvasc, Amlodipine. Can Trazadone Be Taken?

Hi: I am in the midst of my Dr.s trying to control my blood pressure. In the meantime I have anxiety through the roof. At the moment I am on 1.0 of clonidine half three times a day along with other meds all to no avail as of yet. I was wondering if I can take 50 mg's of trazadone for sleep at night or 100 mg's if I need it. I feel horrible and so anxious and can't sleep. I also get the chills, could that be a side affect from one of my meds.? I am on lotensen, benicar in which I am going off of that tomorrow and the Dr. is going to try edarbi, norvasc and amlodipine.
