anxiety
"Very helpful in reducing anxiety for me.  It is fast-acting, and it made a difference in me being able to keep up with my job.  Now, I'm on Klonopin though since the doctor said that it stays in the system longer for anxiety.  However, the fast relief of Xanax works very well when an immediate spike in anxiety happens.  The effects usually only last a few hours for me, and I can understand how it can be addictive for this reason, but it's been great for immediate panic symptoms and helpful with focusing.  I did not notice that "drugged up," foggy feeling on a small dose of .5 mg-1 mg as needed."
