Do you take it? I take it as needed, when I feel anxious and can't shake it.
Have you had complications? Never had complications.
Do you take it everyday? I started taking it every day, and it helped me get into a calm mode so that I could think clearly without the feeling of "something's wrong, something's going to happen, I'm so nervous", ect. After about 2 weeks, my Cymbalta kicked in (for Generalized Anxiety Disorder), and so now I only take Xanax when I get breakthrough anxiety, which isn't too often. I always take it when I fly.
What does it do? It takes the edge off, makes me feel calm, makes me able to function without worrying about everything.
I have to say Xanax was a life-saver for me. I suffered for years with anxiety before I got help.
There's a risk of dependency, but I personally don't take it often enough for that. I know others who take it every day, and will probably do so for the rest of their lives, because they'd rather be dependent on Xanax than going through each day with anxiety, which can really make life hell.
Some people need it for situational reasons, like losing a loved one, going through a divorce, ect, and some people have a chemical imbalance that pre-disposes them to rushing adrenalin, and so they need the Xanax to counteract that. Adrenalin being pumped into your system everyday is dangerous for your health.
