I get extreme anxiety while on... which is always, so I'm learning to cope with it. I've always had stress issues, but I can say AS does indeed exaurate it. Some days I'm obsessive compulsive from the anxiety. I don't think AS will induce anxiety, just like any other genetic factor(hair loss, acne, gyno), but if you're prone to it it may enhance the feelings of anxiety.
...No medical proof on this one. Just what I've been able to determine.
