Sleeping pills and alcohol is a popular way to overdose and pass away. It also happens to be the preferred suicide method by women. Due to this the potency of sleeping pills has been lowered over the years to make them less deadly. Tylenol and alcohol work the same way but is also painful just like sleeping pills. It doesn't exactly lul you to a soothing death. Brain begins to swell and severe liver damage occurs. If you a person lives they'll have long term damage. Cyanide has a more successful rate of suicides. Somewhere in the 90% chance. It is also one of the most painful methods and ends a persons life on average within a minute and a few seconds.
A ridiculous amount, followed by hours of feeling sick, worse than being drunk..... then surviving with long term organ damage and wishing you had found a better way to live. mx:))
Depends on what type, your body weight, and if you add alcohol.
