I was on Ativan 4 mg per day and still walking and talking. I did wean off it by using Valium substitute as it is longer acting and I am now using 2-4 mg of Valium per day when necessary.
10 mg of Valium is equal to 1 mg of Ativan approximately.
I did a very slow wean under my physician's care and had no bad withdrawal.
Hope this helps you.
