We have a lot of people who asks about lethal doses for Clonazepam. I found this on a quick search:
On Quora, from a scientist:
The LD50 of Clonazepam is expected to be as high as 4000 mg/kg.
Clonazepam belongs to a group of anxiolytics called benzodiazepines. They are the successors to barbiturates. Barbiturates have largely grown out of use in modern psychiatry because of the dangers with taking large doses of them.
Benzodiazipines are used because they are safe even when taken in disgustingly large doses.
If you do the math, in order to die, if you weighed 80 kg, you would have to take 320,000 mg of k-pins to have a chance. (That's 160,000 2mg green footballs)
On a website:
Some research has shown it may take more than 4000mg of clonazepam to experience a lethal overdose. However, taking more than your prescribed amount or abusing your medication can still cause dangerous overdose symptoms.
Other website:
Clonazepam is very hard to overdose on when used alone, and a potentially fatal overdose typically occurs only due to an interaction with other substances in the system. According to recent research from the Centers for Disease Control and Prevention, more than 10,500 people died in 2016 from an overdose that involved benzos.
As for Eszopiclone, it's essentially the same as Zolpidem which is even safer:
According to US Prescribing Information, overdoses of eszopiclone with intakes up to 90 times the recommended dose have been reported and there has been full patient recovery, so it is a safe substance to overdose.
Those medications are safe to use and it's really hard to cause a lethal overdose. It could potentially put you in coma, but it's still very hard. Most probably you will end up with a very bad headache and dizziness.
