I have been diagnosed with GAD too. I guess I would say mine is constant too, but I am able to function.

I have been almost on every antidepressant available, but nothing has helped. I've taken ativan, but that knocks me out. Has anyone taken Buspar? One of my docs recommended Valerian Root, so I have been trying that. They have plain Valerian and also Valerian with "calming" ingredients like hops, etc. I've found the latter to work good for insomnia on those rare nights when I can't sleep.
