Ativan is in the same family as Xanax but they are not the same med. Ativan is one of the strongest and shorter acting of the benzos. Can you become addicted, yes you can and it is a med that I used and was at the max dose of 4 mg/day. I weaned off it by switching to Valium through my Pdoc. 4mg of Ativan = 40 mg of Valium. I am at 2 mg of Valium now.
If the Ativan is not working I would visit with your physician about switching to Valium as it is a much longer acting drug.
I worked full time on a benzo as long as you know you are able to function and do not have to deal with dangerous equipment, there may be no problem for you.
