Hi, it’s possible but not a good idea because it’s a big step in a short time, I would like to ask you how long have you been taking Ativan and perhaps what doctor prescribed it for you and why, lots of questions but relevant. At this point I’m inclined to say that you need to see your doctor and discuss your decision to taper off the medication and maybe get some help with it. There are many discussions about this subject here and you can find many other people who have been doing this too, best wishes.
