Daily use of benzos is extremely bad in general - the physical addiction is not pleasant to withdraw from, and it significantly increases the risk of dementia in old age.
Spoke to a psychiatrist on this one. He was saying The Lancet longitudinal study was bunk and that Xanax use was not one of concern.
I'm not saying he's correct, but he literally laughed at my objection to Xanax, including it's now very long history of use with an average dose of 6mg/day.
I still use a benzo (lowest dose lamictal) but only about once a month when I need hit the panic button. It's really not meant to be a daily use drug, scared me when a friend was prescribed it as a daily medication.
Not saying that proves anything, but it was scary.
