Any idea how to kill yourself?

I was about to see this young lady in the Emergency Room and I saw the nurse's short note "Patient here for suicidal attempt. Had a fight with her boyfriend then swallowed 8 pills of valium and drank half a bottle of vodka. She says "I want to die today" "

I checked her hospital chart, she had seven previous suicidal attempts in the past by swallowing a few pills and drinking alcohol. She always ends up being admitted for a month or so to the psychiatry unit then discharged home, then she would have a fight with someone and take a few pills and come to the hospital saying that she tried to commit suicide and that she wanted to die.
This seemed to never end.

My attending physician (my boss) caught me,
"So Masannat what's your plan for her?"
"I'll admit her to the ICU for observation tonight, if she's stable tomorrow she'll go to the psych unit"
"Cool, love this plan"
"I'll also tell her that our hospital has ten floors, if she decides next time to kill herself she should forget about the pills and go up the tenth floor and throw herself up from there".

I was excused from seeing her.
