Tenex (guanfacine) for anxiety?

Has anyone taken Tenex (guanfacine) for symptoms of anxiety, and if so could you please share your experience.  Thanks.

I take Tenex for severe anxiety. It has been the miracle addition to my medication regime  I've had unbearably severe anxiety that hasn't responded well to SSRI's or atypical antipsychotics.  Right now I'm taking Tenex with Effexor and Seroquel (low doses on each), and it has made such an amazing difference.  I don't feel drugged or strung out on it, though immediately after taking it I have had some cases of orthostatic hypertension (getting up too quickly and getting very dizzy and faint).  There are studies in progress for Tenex for severe anxieity and it's been used for a while with patients with PTSD so far as I know.  I'm sure it's not for everyone but I'm guessing if it's been suggested it's due to a situation like mine where the typical options just weren't cutting it.  I hope this helps some... It's really made a difference in the manageability of my disorder...
