L.,
I am not sure if any members currently are, or have taken Vortioxetine/Brintellix/Trintellix.
If you do not get responses here, you could try posting in the Depression Forum as well for input. They may not be able to tell you how it performs specifically for anxiety...since they are likely taking it more for depression...but you may get a general idea of whether your experience is typical, what to expect, ect...
Best wishes and keep us updated on your progress.
