Anxiety
"This med causes me severe headaches and helps with anxiety some but the pain in my head only grows worse each day along with blurred vision and highly increased appetite and dry mouth. Not worth the daily headaches. Using an antihistamine for anxiety and blood pressure meds like clonidine, said to help with my adhd that does nothing for my focus,  is a mixture of insanity. Im over the vistaril after a month of more intense headaches everyday."
