If your going to take a serious overdose you should be aware of what might happen before you die. This isnt like throwing yourself off a cliff or shooting yourself. Once youve taken the drugs in any serious amount, there's a slim chance your going to survive unless you throw up and get yourself to A&E. What's more, imagine if you took the overdose then realised that youve done the wrong thing. Imagine the pain in your mind, would you really want to die in such inconsolable fear and misery?
