I have to be honest the only thing
That calms my extreme anxiety is diazapam which My GP let's me have when things get bad, and 28 last about 3 months. To be honest does it matter if I get addicted at age 75. I still take my citalapram regularly.
I took it for a while for reactive depression after a bereavement. The doctor told me it's one of their most widely prescribed drugs. I have a friend who took it for anxiety but it didn't really work so she was switched to Sertraline which worked much better.
that's what I tell my GP sometimes, pat: who cares if I come to depend on something like sleeping pills, it's not like I have thousands of nights left.
