It really is different for everyone. I take 0.5 mg of Ativan twice a day, and I feel this is a decent dosage as I become moderately sedated and calm with it. I tried 1 mg of Xanax (the supposed equivalent of 4 of my dinky 0.5 mg Ativan pills) and did not feel as calm as I do when I take my normal dosage of Ativan, even though most people feel Xanax is the more potent benzo.
