My brother is 50 and does not look well. He has been saying it is his blood pressure medication. He hasn t been taking them for several months but still has the same symptoms. He claims that he is not drinking or doing drugs but I am not sure. My family is very concerned. Symptoms: shaking hands, sweating profusely at times, telling the same story repeatedly, not eating much, irregular sleep, not doing ANY work/maintenance around the house, goosebumps when it is hot and muggy. These symptoms are almost continuous. Any thoughts?
