It can be used as a treatment for anxiety, with similar effects to benzodiazepines. However, it takes a period of regular dosage for this to take effect, it's not like taking a single tablet will calm you down immediately (like a benzo might). You need to be on the correct dosage for a while.
Once again, if you have
not been personally prescribed it, I would be
very wary of using it recreationally, especially on an ongoing basis, without proper medical guidance. It has a number of potential side effects, as well as withdrawal effects.
