I was on Xanax for the past two months. I was taking between 4-6 mg a day with a few days in between where I did not take as much or any at all. Yesterday my Doctor took me off the Xanax and put me on Valium 5 mg twice a day. I don"t want to be on any benzo's at all anymore but I guess my question is, is it safe to drop that much that quickly after two months? He told me to take the 15 day supply of valium and that should be good enough. I am still concerned about it though. I heard you can have terrrible withdrawals from Xanax after a few weeks.
