No one on this site will provide the information you request because it would be unethical and irresponsible to do so. The fact is far more suicide attempts end in long term disability than death and even if you find someone claiming to know an effective dose they are lying or mistaken. We see people with levels of drugs in their blood 2-3 times levels considered lethal who live and people with moderate to high levels who do not. Whatever your reason for this suicidal gesture I hope and I will pray that you will stop and look for help and at very least you will not risk a fate worse than death. Please call the suicide hotline at

I hope it means something to you that you reached out and a total stranger cares whether you live or die. I don't expect to be paid since this is not a direct answer to your question and so I am taking this time for no other reason than to offer my support and express my concern.
