Ambien is specifically designed to help you sleep while
Xanax can help, it is prescribed for anxiety. Also, remember, that
you can build a tolerance up with xanax...If you are still concerned, why not talk with your pharmacist that fills your prescription? They usually have a wealth of knowledge that you can tap into in my opinion. I have used it a couple of times and it worked...just ensure you have a fairly good chunk of time blocked off for sleep. Keep us posted!
