Hate to be the bearer of bad news but most people do better on a real benzo than any anti histamine , any anti psychotic or SSRI , but since some how addictionology has been put in Psychiatry's corner alot of doctors are paranoid about using them ,just as many chronic pain patients cant find care if they require opioids patients eith anxiety and panic can't find benzo frequently . Drug abuse and addiction are being falsely conflated with properly cared for patients who take benzo and opioids responsably and correctly , lots of years of evidence and studies prove this out, yet these drugs are unfairly demonized and patients don't receive life changing and life saving care by providers . Sorry for the rant , it's a major aggravating peeve of mine ,medication doesn't help anyone sitting on shelf because providers don't want to learn to use it appropriately or devout the time to patients care .
