I take the same dosage of Xanax as you do, however, I don't take it every day. I don't feel addicted to it, but it does help to take the edge off when I feel the need and works. I too have heard that it is dangerous, but again, I don't take it everyday--- in fact, I think I took it more when I was drinking then I do now, which is bad news.
Everyone is different and reacts differently to meds. Xanax works for me after trying many others that had adverse effects.
