I take Ativan every day because I have huge amounts of anxiety. My doctor does not like prescribing it and is always trying to lower the dose or amount of pills. That's fine. The latest batch is marked ATIVAN on the prescription lable but the pills are a different size, no identifying marks, tastes different but mostly I do not notice any effect. I didn't notice the difference in the pills until I started noticing the lack of feeling better after taking them. I've taken two at a time and no difference. If I took two at a time a month ago, I would be sound asleep within an hour. I normally take 1/2 once per day.
