Ativan is extremely difficult to overdose on. Those days are long gone.
The LD50 (lethal dose on average) for Ativan is around 2000 mg per kg of body weight.
You would throw up well before even reaching that point (potentially inhale some of your own vomit and suffocate from that).
What can also happen (and I can tell you that from personal experience) is that you are so out of it that your reflexes are subdued by the drug. You can seriously injure yourself by unconsciously laying on one side, blocking blood flow in and out of your arm for example, for an extended period of time.
If you are unable to feel your arm tingling and move your position, you'll eventually get something called "compartment syndrome".
That's extremely painful and can lead to longtime physical disability.
Acute compartment syndrome is a serious condition that involves increased pressure in a muscle compartment. It can lead to muscle and nerve damage and problems with blood flow.
